This Electronic Hub Will hopefully demystify the basics of electronics so that anyone with an interst in Circuit making can hit the Gund running.

There are 2-type of electronic singals, those being alternating current (AC), and Direct Current (DC).

with alternating current, the direction electrcity flows throughtout the circuit is constantly reversing. You may even say that it is alternating directon. The Rate of reversal is measured in Hertz, Whice is the mumber of reversals per scond. Th US power supply is 60 Hz,what they mean is that is reversing 220 timers per second (twice per cycle).

with Direct Current, Electricity flows in 1 direction between power and fround. In this arrangement there is always a positive source of voltage and ground (0v) source of voltage. You con test this by reading a battery with with multimeter.

Circuts: A Circuit ios complete and closed path throught which electric current can flow. In other words, a closed circuit would allow the flow of electricity between Power and Ground. An Open Circuit would break the flow of electricity between power and Ground.

Anything that is part of this closed system and that allows electricity to flow between power and fround is considered to be part of the circuit diagram

Resistance: The next very Important consideration to keep in mind is that electricity in a circuit must be used.

The Circuit above, the motor that electricity is flowing throught is adding resistance to the flow of electricity. This all of the electricity passing throught the circuit is being pur to use.

Also note that a switch does not add any resistance to a circuit and simply adding a switch between power and Ground will create a short circuit.

Series Vs. Parallel: There are 2 different ways in which you can wire things togerher called serics and parallel. when things are wired in serics, things are wired one after another, such that electricity has to pass through one thing, then the next thing, then the next, and so on.

When things are wired in parallel, they are wired side by side, such that electricity passes through all of them at the same time, from one common point to another common point.

In the first example, the motor, switch and battery are all wired in series because the only path for electricity to flow is from one, to the next, and to the next.

In the next example, the motors are wired in parallel because the electricity passes through both motors from one common point to another common point.

in the final example the motors are wired in parallel, but the pair of parallel motors, switch and batteries are all wired in series. So, the current is split between the motors in a parallel fashion, but still must pass in series from one part of the circuit to the next.

If this does not make sense yet, do not worry. When you start to build your own circuits, all of this will start to become clear.

Basic Components:

In order to build circuits, you will need to become familiar with a few basic components. These components may seem simple, but are the bread and butter of most electronics projects. Thus, by learning about these few basic parts, you will be able to go a long way. Bear with me as I elaborate as to what each of these are in the coming steps.

Transistors:

A transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A transistor can act as a switch or gate for electronic signals, opening and closing an electronic gate many times per second. It ensures the circuit is on if the current is flowing and switched off if it isn't. Transistors are used in complex switching circuits that comprise all modern telecommunications systems.

Capacitors:

A capacitor is a component that stores electricity and then discharges it into the circuit when there is a drop in electricity. You can think of it as a water storage tank that releases water when there is a drought to ensure a steady stream.

The most commonly encountered types of capacitors are ceramic disc capacitors that look like tiny Me and Ms with two wires sticking out of them and electrolytic capacitors that look more like small cylindrical tubes with two wires coming out the bottom (or sometimes each end).

Capacitors are measured in Farads. The values that you will typically encounter in most capacitors are measured in picofarad (pF), nanofarad (nF), and microfarad (uF). These are often used interchangeably and it helps to have a conversion chart at hand.

Ceramic disc capacitors are non-polarized, meaning that electricity can pass through them no matter how they are inserted in the circuit. They are typically marked with a number code which needs to be decoded. Instructions for reading ceramic capacitors can be found here. This type of capacitor is typically represented in a schematic as two parallel lines.

Electrolytic capacitors are typically polarized. This means that one leg needs to be connected to the ground side of the circuit and the other leg must be connected to power. If it is connected backwards, it won't work correctly. Electrolytic capacitors have the value written on them, typically represented in uF. They also mark the leg which connects to ground with a minus symbol (-). This capacitor is represented in a schematic as a side-by-side straight and curved line. The straight line represents the end which connects to power and the curve connected to ground.

Inductors:

An inductor is a passive component that is used in most power electronic circuits to store energy in the form of magnetic energy when electricity is applied to it. One of the key properties of an inductor is that it impedes or opposes any change in the amount of current flowing through it.Choking, blocking, attenuating, or filtering/smoothing high frequency noise in electrical circuits. Storing and transferring energy in power converters (dc-dc or ac-dc).inductors with air cores, iron cores, ferrite cores, iron power, variable, coupled, and molded cores. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a magnetic field in the clockwise direction.The design of an inductor is governed by electrical, mechanical, and thermal requirements of a given application. In general, it involves: Selecting the core material Deciding a core shape and size Selecting a winding wire The core material is an enamel-coated magnetic wire typically made of copper which is then coated in layers of insulating polymer material. The winding can form many shapes, including circular, rectangular foil, and square cross-section.

Diode:

An electrical component that only enables current to travel in a single path is called a diode. It is represented by a triangle with a line across one vertex.A diode is an electronic component that directs the flow of electricity in a single direction. These are called "active components" and are basic components of semiconductors. They can regulate the flow of electricity, maintain a constant voltage, and extract signals from radio waves.Diodes are used in circuit protection due to their ability to restrict electrical current to flow in only one direction. This trait is useful because some electrical components and devices will be damaged or malfunction if current flows in the wrong direction.Diodes are used in circuit protection due to their ability to restrict electrical current to flow in only one direction. This trait is useful because some electrical components and devices will be damaged or malfunction if current flows in the wrong direction. For example, current problems can cause microprocessors to experience erroneous calculations or simply short out and fail. The diode can be used to not only protect from stray currents, but can be electrically routed to redirect the stray currents into useful current.

Mosfet:

MOSFETs are electronic devices used to switch or amplify voltages in circuits.MOSFET is a field-effect transistor (FET with an insulated gate) where the voltage determines the conductivity of the device. It is used for switching or amplifying signals. The ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals.The working principle of a MOSFET depends upon the MOS capacitor. The MOS capacitor is the main part of MOS-FET. The semiconductor surface at the below oxide layer is located between the source and drain terminals. It can be inverted from p-type to n-type by applying positive or negative gate voltages. The depletion region is populated by the bound negative charges that are associated with the acceptor atoms. The electrons reach, and the channel is formed. The positive voltage also attracts electrons from the n+ source and drain regions into the channel. Now, if a voltage is applied between the drain and source, the current flows freely between the source and drain and the gate voltage controls the electrons in the channel. If we apply negative voltage, a hole channel will be formed under the oxide layer.

Electronic Overview:

The industrial electronics industry manufactures electronic equipment for industrial purposes. Industrial electronics systems include everything from simple components like drives, sensors, and switches to sophisticated power converting technologies, PLCs and robotics.Electricity occurs in nature in thunderstorms, electric eels and static electricity. Numerous experiments and discoveries have framed our modern day understanding of electricity. but not everyone has the understanding they want of all things electrical and electronic.

This guide is designed to help directors and managers to better understand electricity and electronics. These include the Ancient Greeks discovering static electricity by rubbing fur on amber; Benjamin Franklin flying a kite in a thunderstorm; Alessandro Volta’s discovery that certain chemical reactions could produce electricity leading to an early battery; Michael Faraday creating the electric dynamo; Swan and Edison both inventing the electric bulb; Nikola Tesla’s alternating current induction motors; Guglielmo Marconi pioneering long range radio transmissions; Gauss’s law for magnetism; and more. Electrical and Electronic Engineering today is truly standing on the shoulders of giants.

Electricity is harnessed and put to work in games, toys, machines, communications, healthcare, vehicles, security, computing, lighting, heating, control and more but what is electricity?

.

Electricity is the flow of charge. Everything in the world is made up of tiny atoms. These atoms are made up of protons, neutrons and electrons. The electrons are in orbit around the atom and when sufficient force is applied these electrons can escape the orbit and become free. Within an atom Protons have a positive charge and electrons have a negative charge. Moving a negative charge electron from an atom leaves the atom with a positive charge. Charles-Augustin de Coulomb first published a law relating stationary electrically charged particles and the interaction force between them. Materials can be broadly classified as conductors or insulators depending upon how tightly its electrons are bound to its atoms. Conductors have weakly bonded electrons, insulators have strongly bonded electrons. Metals including gold, silver and copper have weakly bound electrons and so are good conductors. Conversely rubber, plastic, glass and air have tightly bound electrons and so are good insulators. Both conductors and insulators are important to control the flow of charge. There are two other types of conductor namely semi-conductors and super conductors. Semi-conductors are used extensively used throughout modern electronics and will be covered in later sections.

Electricity:

Electricity is a type of energy that consists of the movement of electrons between two points when there is a potential difference between them, making it possible to generate what is known as an electric current.Electric power is the rate at which work is done or energy is transformed into an electrical circuit. Simply put, it is a measure of how much energy is used in a span of time.The two kinds of electricity are: Static electricity: The imbalance between the positive and negative charges within an object causes the discharge of an electrical pulse known as Static Electricity. Current electricity: Current electricity is defined as the flow of electrons from one section of the circuit to another.In electricity the particle involved is the electron, which carries a charge designated, by convention, as negative. Thus, the various manifestations of electricity are the result of the accumulation or motion of numbers of electrons. Electrostatics is the study of electromagnetic phenomena that occur when there are no moving charges—i.e., after a static equilibrium has been established. Charges reach their equilibrium positions rapidly because the electric force is extremely strong. The mathematical methods of electrostatics make it possible to calculate the distributions of the electric field and of the electric potential from a known configuration of charges, conductors, and insulators. Conversely, given a set of conductors with known potentials, it is possible to calculate electric fields in regions between the conductors and to determine the charge distribution on the surface of the conductors. Finally, energy can be stored in a capacitor; the energy required to charge such a device is stored in it as electrostatic energy of the electric field.

Led:

A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. When current passes through an LED, the electrons recombine with holes emitting light in the process.LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light.

The Different colors Inside the semiconductor material of the LED, the electrons and holes are contained within energy bands. The separation of the bands (i.e. the bandgap) determines the energy of the photons (light particles) that are emitted by the LED. The photon energy determines the wavelength of the emitted light, and hence its color. Different semiconductor materials with different bandgaps produce different colors of light. The precise wavelength (color) can be tuned by altering the composition of the light-emitting, or active, region. LEDs are comprised of compound semiconductor materials, which are made up of elements from group III and group V of the periodic table (these are known as III-V materials). Examples of III-V materials commonly used to make LEDs are gallium arsenide (GaAs) and gallium phosphide (GaP). Until the mid-90s LEDs had a limited range of colors, and in particular commercial blue and white LEDs did not exist. The development of LEDs based on the gallium nitride (GaN) material system completed the palette of colors and opened up many new applications. Main LED materials- The main semiconductor materials used to manufacture LEDs are: Indium gallium nitride (InGaN): blue, green and ultraviolet high-brightness LEDs Aluminum gallium indium phosphide (AlGaInP): yellow, orange and red high-brightness LEDs Aluminum gallium arsenide (AlGaAs): red and infrared LEDs Gallium phosphide (GaP): yellow and green LEDs

Switch:

An electrical switch is any device used to interrupt the flow of electrons in a circuit. Switches are essentially binary devices: they are either completely on (“closed”) or completely off (“open”). There are many different types of switches, and we will explore some of these types in this chapter.

Switch is an electrical component which can make or break electrical circuit automatically or manually. Switch is mainly works with ON (open) and OFF (closed) mechanism. Numerous circuits hold switches that control how the circuit works or actuate different characteristics of the circuit. The classification of switches depends on the connection they make. Two vital components that confirm what sorts of connections a switch makes are pole and throw.

These are classified on based the connections they make. If you were under the impression that switches simply turn circuits on and off, guess again. The terms pole and throw are also used to describe switch contact variations. The number of “poles” is the number of separate circuits which are controlled by a switch. The number of “throws” is the number of separate positions that the switch can adopt. A single-throw switch has one pair of contacts that can either be closed or open. A double-throw switch has a contact that can be connected to either of two other contacts; a triple-throw has a contact which can be connected to one of three other contacts, etc.

Transformer:

Transformertransformer is an electrical device that uses the principle of electromagnetic induction to transfer energy from one electric circuit to another. It is designed to either increase or decrease AC voltage between the circuits while maintaining the frequency of the current.

transformer is a device used in the power transmission of electric energy. The transmission current is AC. It is commonly used to increase or decrease the supply voltage without a change in the frequency of AC between circuits.

are the three functions of a transformer? The main function of the power transformer is to change the voltage and voltage, realize the transmission of electric energy, and realize long-distance transmission.In its most basic form a transformer consists of: The primary winding (coil), which receives energy from the AC source. The secondary winding (coil), which receives energy from the primary winding and delivers it to the load. The core, which provides a path for the magnetic lines of flux.For example, many cell phones, laptops, video games, and power tools and small appliances have a transformer built into their plug-in unit (like that in Figure 1) that changes 120 V or 240 V AC into whatever voltage the device uses.

Relay Switch:

A simple relay consists of wire coil wrapped around a soft iron core, or solenoid, an iron yoke that delivers a low reluctance path for magnetic flux, a movable iron armature and one or more sets of contacts. The movable armature is hinged to the yoke and linked to one or more set of the moving contacts.

A relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current. The heart of a relay is an electromagnet (a coil of wire that becomes a temporary magnet when electricity flows through it).

Relay Features Relay Features.There are many features in our Parametric Filter for choosing a relay for your application. Lighted Indicator. Example: Mechanical Indicator. Test Button. Resistor. Diode,Surge Protection, Varistor and RC Circuit. Debounce Delay. Magnetic Blowout. A relay is an electrically operated switch. They commonly use an electromagnet (coil) to operate their internal mechanical switching mechanism (contacts). When a relay contact is open, this will switch power ON for a circuit when the coil is activated. The example relay diagrams below show how a relay One of the most common situations that require the use of a relay occurs when an application needs to switch from high to low current (or vice versa) within the same circuit. For example, the temperature sensors that power HVAC units require levels of amperage that vastly exceed the capacity of their wiring.

IC:

An integrated circuit (IC), sometimes called a chip, microchip or microelectronic circuit, is a semiconductor wafer on which thousands or millions of tiny resistors, capacitors, diodes and transistors are fabricated.

Why is IC called IC? Integrated Circuit - Definition, Construction, Features ... Because they combine various devices on one chip, integrated chips get their name. A microcontroller is an integrated circuit (IC) that combines a microprocessor, memory, and interface into a single unit.integrated circuit (IC), an assembly of electronic components, fabricated as a single unit, in which miniaturized active devices (e.g., transistors and diodes) and passive devices (e.g., capacitors and resistors) and their interconnections are built up on a thin substrate of semiconductor material (typically silicon).Example of Integrated Circuit: Microprocessors in computers, memory chips in mobile phones, and controller chips in consumer electronic devices.

IGBT:

IGBT stands for insulated-gate bipolar transistor. It is a bipolar transistor with an insulated gate terminal. The IGBT combines, in a single device, a control input with a MOS structure and a bipolar power transistor that acts as an output switch.

IGBT is a three-terminal power semiconductor device primarily forming an electronic switch. It was developed to combine high efficiency with fast switching. It consists of four alternating layers (P–N–P–N) that are controlled by a metal–oxide–semiconductor (MOS) gate structure.high reliability and high efficiency with high short circuit tolerance (tsc) and low saturation voltage, collector-emitter or VCE(sat).the working of the IGBT, consider a voltage source VG connected positively to the Gate terminal with respect to the Emitter. Consider other voltage source VCC connected across The Emitter and the Collector, where Collector is kept positive with respect to the Emitter. Due to the voltage source VCC the junction J1 will be forward-biased whereas the junction J2 will be reverse biased. Since J2 is in reverse bias there will not be any current flow inside the IGBT(from collector to emitter).Initially, consider that there is no voltage applied to the Gate terminal, at this stage the IGBT will be in a non-conductive state. This will lead to a formation of the channel between the J2 junction which allows the flow of current from collector to emitter. The flow of current is represented as the current path in the picture, when the applied Gate voltage VG increases the amount of current flow from the collector to the emitter also increases.

Microphone:

The microphone commonly consists of a magnetic (moving coil) transducer, contact plate and contact pin. The contact plate is placed directly on the vibrating part of a musical instrument or other surface, and the contact pin transfers vibrations to the coil.

microphone is an electroacoustic device that converts acoustic energy into electrical energy. This conversion occurs via a mechanical system, usually a diaphragm, set into oscillations by a sound field.Types Of Microphones - Condenser, Dynamic, And Ribbon. There are three primary types of microphones. Those include cardioid, dynamic, and ribbon microphones. Ideally, they all work the same but are designed to capture different elements.microphones use their diaphragms to pick up sounds and convert them into electrical currents. A microphone converts sound into a small electrical current. Sound waves hit a diaphragm that vibrates, moving a magnet near a coil. In some designs, the coil moves within a magnet.

Fuse:

In electrical and electronics, a fuse is defined as an electrical safety device that provides over-current protection to the functional electrical circuit. The fuse wire is chosen such that it has a low melting point.

Fuses are basic safety devices widely deployed in electrical circuits for excess current or overcurrent protection. If a stronger than expected current surges through, the fuse will blow and break the circuit, minimising heat damage and reducing the risk of electrocution or fire. This is called tripping a circuit.fuse is a service that delivers usable electrical circuit over-current safety. Some of the main fuse functions are as follows: Acts as a barrier between both the human body and the electric circuit. Inhibits system failure due to defective operation of circuits. Fuse avoids short-circuits.Electric fuse works on the principle of the heating effect of electric current. It is placed in series with the device. A fuse consists of a piece of wire made of a metal or an alloy of an appropriate melting point, for example, aluminum, copper, iron, lead etc.

Battery:

Battery, in electricity and electrochemistry, any of a class of devices that convert chemical energy directly into electrical energy. Although the term battery, in strict usage, designates an assembly of two or more galvanic cells capable of such energy conversion, it is commonly applied to a single cell of this kind.

electrochemical cell: Basic components of an electrochemical cell. Every battery (or cell) has a cathode, or positive plate, and an anode, or negative plate. These electrodes must be separated by and are often immersed in an electrolyte that permits the passage of ions between the electrodes. The electrode materials and the electrolyte are chosen and arranged so that sufficient electromotive force (measured in volts) and electric current (measured in amperes) can be developed between the terminals of a battery to operate lights, machines, or other devices. Since an electrode contains only a limited number of units of chemical energy convertible to electrical energy, it follows that a battery of a given size has only a certain capacity to operate devices and will eventually become exhausted.See all videos for this article Commercially available batteries are designed and built with market factors in mind. The quality of materials and the complexity of electrode and container design are reflected in the market price sought for any specific product. As new materials are discovered or the properties of traditional ones improved, however, the typical performance of even older battery systems sometimes increases by large percentages.

Loudspeaker:

loudspeaker is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound.

loudspeaker, in sound reproduction, device for converting electrical energy into acoustical signal energy that is radiated into a room or open air.loudspeaker used in public places for announcing things, playing music, etc.Speakers are standard output devices used with computer systems that enable the listener to listen to a sound as an outcome. Some speakers are used once they have been linked to a computer, while others may be connected to any type of sound system.Loudspeaker specifications have traditionally described the physical properties and characteristics of loudspeakers: frequency response, dimensions and volume of the cabinet, diameter of drivers, impedance, total harmonic distortion, sensitivity, etc.The speaker is simply the person who is delivering, or presenting, the speech. A speaker might be someone who is training employees in your workplace. Your professor is another example of a public speaker as s/he gives a lecture. Even a stand-up comedian can be considered a public speaker.

Antenna:

An antenna is a metallic structure that captures and/or transmits radio electromagnetic waves. Antennas come in all shapes and sizes from little ones that can be found on your roof to watch TV to really big ones that capture signals from satellites millions of miles away.

antenna is a device that is made out of a conductive, metallic material and has the purpose of transmitting and/or receiving electromagnetic waves, usually radio wave signals. The purpose of transmitting and receiving radio waves is to communicate or broadcast information at the speed of light.Definition: Antennas are devices that transmit or receive electromagnetic (EM) energy in a way suitable for a specific application. Examples of EM energy: Light waves, radio waves, cell phone signals, microwave oven power sources, radar signals.Antennas are devices that are used to transmit and receive electromagnetic waves. An antenna is a device that transmits and/or receives electromagnetic waves.In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment.

A few older Americans, at least in New England might still call it the “Clicker”. Some of the early remotes made different clicking noises that the TV recognized as a command to change the channel or volume. So it got called a clicker.Remote work is the practice of employees doing their jobs from a location other than a central office operated by the employer. Such locations could include an employee's home, a co-working or other shared space, a private office, or any other place outside of the traditional corporate office building or campus.Remote work provides the freedom to work from anywhere that the company is legally authorized for employment. Virtual work takes it a step further by eliminating the traditional office entirely.

Board:

The circuit board is the backbone of a computer, as it allows all of the different components to communicate and work together. It is typically made of layers of conductive material, such as copper, that are laminated together to form a flat, rectangular board.

A printed circuit board (PCB) is an electronic assembly that uses copper conductors to create electrical connections between components. PCBs also provide mechanical support for electronic components so that a device can be mounted in an enclosure.With so many different industries and devices utilizing PCBs, the construction of these critical components has evolved. There are now six different types of printed circuit boards, including: Single-sided. Double-sided.The main circuit board of a modern computer is called a motherboard. It works by providing a platform for the components to be mounted and interconnected, allowing electrical signals to flow between them and enabling the functioning of electronic devices.The PCBs are mainly used to provide electrical connection and mechanical support to the electrical components of a circuit.

Optocoupler:

An optocoupler (also called optoisolator) is a semiconductor device that allows an electrical signal to be transmitted between two isolated circuits. Two parts are used in an optocoupler: an LED that emits infrared light and a photosensitive device that detects light from the LED.

Optocouplers are often referred to by their "output type"; for example, a phototransistor device might be called an optocoupler "with phototransistor output."A commonly used optocoupler is the ON Semiconductor 4N25 (formerly Fairchild), as shown in Figure 1. Optocouplers provide complete electrical isolation between circuits at the input and output terminals of the optocoupler.

Advantages of Optocoupler: Compact and less weight. Low cost. Works very fast. Less noise. The optocoupler works well on either AC or DC high-voltage signals. It is also used in a number of sensor applications to sense the presence of physical objects. The lifetime of optocouplers can exceed several decades.The gain of the optocoupler is expressed as a current transfer ratio (CTR), which is the collector current (IC) of the output divided by the forward current (IF) of the input and multiplied by 100 %.

Power Sensor:

A Power Sensor measures either current or voltage and provides output on monitored parameter levels to a control system. Current sensors are capable of measuring both AC and DC current, in order to monitor power use and provide diagnostics for electrically-powered equipment.

A sensor is a device that detects and responds to some type of input from the physical environment. The input can be light, heat, motion, moisture, pressure or any number of other environmental phenomena.Five main sensors: eyes, ears, nose, skin, tongue. (Other sensors include: detecting temperature, detecting body position, balance sensors, and blood acidity sensors.)8 Sensors Every Smart Home Needs Temperature Sensors and Smart Thermostats.Light Sensors.Motion Sensors.Water Leak/Freeze Sensors.Window and Door Sensors.Video Doorbell.Weather Sensors.Smart Smoke and CO Sensors.he Huawei smart power sensor provides an accurate, simple and efficient way of allowing the inverter to monitor home consumption for export limitation or battery system operation. Different models of microwave USB power sensors conduct accurate modulated power measurements on many types of signals including, but not limited to, WCDMA, LTE, and WLAN.

Current Sensor:

A current sensor detects and measures the electric current passing through a conductor. It turns the current into a quantifiable output, such as a voltage, current, or digital signal, which may be utilised in a variety of applications for monitoring, control, or protection.

A current sensor is a device that detects electric current in a wire and generates a signal proportional to that current. The generated signal could be analog voltage or current or a digital output.There are a variety of applications for current sensors. For example, some devices are used for power metering, control system diagnosis, current supply measurement, and the control of complex loads from electric motorsCurrent sensors have a number of features, such as low heat generation, a wide measuring range, an extended bandwidth, high resolution, precision, and a low offsetCurrent is measured by converting the magnetic field generated around the current flow into a voltage (Hall voltage) using the Hall effect.Current sensors provide sensitivity down to 26.7mV/A With provision to be factory calibrated for zero-current output point and sensitivity, each of these devices produces a linear analog output that is proportional to the current flowing directly through the IC's leadframe.A current sensor fault is triggered if the analog voltages from the attached current sensor stray outside of the normal range or if the values from the 2 redundant current sensors do not match.A current sensor is a device that detects and converts current to an easily measured output voltage, which is proportional to the current through the measured path. When a current flows through a wire or in a circuit, voltage drop occurs.A current switch is used to monitor this current level. Just remove the top portion of the sensing ring, place the conductors inside, and snap the top back in place. The transducer uses two wires to connect to the power supply and the load, programmable logic controller, panel meter or data acquisition system.

Temperature Sensor:

Temperature sensors are devices that detect and measure coldness and heat and convert it into an electrical signal. Temperature sensors are utilized in our daily lives, be it in the form of domestic water heaters, thermometers, refrigerators, or microwaves.

The definition of a temperature sensor is essentially an electronic device used to take accurate temperature measurement readings. Temperature sensors are available in different “types”.Attached to the thermostat or installed right next to it is the temperature sensor which looks like a small, black device plugged into a wire harness. The location of your vehicle's temperature sensor may vary depending on your make and model, but generally, it's located next to your thermostat on your engine block.An RTD is more linear than a thermocouple or thermistor and is the most accurate and reliable temperature sensor. Temperature sensors are installed in such applications for consistent temperature monitoring and control.Sensor technology is important because it allows for the detection, measurement, and monitoring of physical, chemical, and biological phenomena in various industries such as healthcare, manufacturing, automotive, and aerospace.

Flow Sensor:

Flow sensors are used to measure the flow rate of blood or oxygen through a vessel. Implantable flow sensors are commonly incorporated into a flexible cuff (Fig. 20.10) that is fitted around the vessel whose flow rate is to be measured.an electronic device component used to measure or regulate the flow rate of gases and liquids in pipes and ducts.

They are commonly used in HVAC systems, medical devices, chemical factories, and septic systems. Flow sensors are able to detect leaks, blockages, pipe bursts, and changes in liquid concentration due to contamination or pollution.Flow sensors and flow meters play a crucial role in various industries and applications, making them essential components in many systems. These devices provide accurate and reliable measurement of fluid flow, which is critical for ensuring efficient processes, improving product quality, and maintaining safety.Differential pressure flow meters are, by far, the most common units in use today. Magnetic Flow Meters: 0.2% – 2% accuracy.The Mass Air Flow sensor is essential for the optimal operation of your vehicle's internal combustion engine. Based on its airflow measurement, the ECU balances air and fuel up. In other words, without a MAF sensor, your car would not work.One of the main limitations is that due to the short wavelength of ultrasound, ultrasonic flow meters are not suitable for measuring liquids containing solid particles.Sensors work by detecting physical changes in the device's environment and output them as analogue voltages or digital signals. This is then sent to a human-readable display where it can be monitored or transmitted, or relayed to other electronic devices for further processing.

Voltage Sensor:

A voltage sensor is a device that measures voltage. Voltage sensors can measure the voltage in various ways, from measuring high voltages to detecting low current levels. These devices are essential for many applications, including industrial controls and power systems.

Temperature Sensors: Temperature is the commonly measured environmental quantity for various reasons

Pressure Sensor:

A pressure sensor is a device that senses and measures pressure. In this case, pressure is defined as the amount of force exerted over an area. Pressure sensors allow for more specialized maintenance strategies, such as predictive maintenance. These devices collect real-time data on the conditions of equipment.

What is the pressure sensor? Pressure sensors are measurement tools for detecting, monitoring, reading and displaying changes in applied pressure from a contained volume of liquid or gas. They can also be used with uncontained volumes, such as atmospheric pressure.There are seven main types of pressure sensors: Aneroid barometer pressure sensors, manometer pressure sensors, bourdon tube pressure sensors, vacuum (Pirani) pressure sensors, sealed pressure sensors, piezoelectric pressure sensors, and strain gauge pressure sensors.Some example applications are: Motorsport Applications – pressure transducers are used for measuring oil, fuel and brake pressure.It may be used to treat various medical ailments, including skin grafts, burn injuries, carbon monoxide poisoning, and decompression sickness in divers. Analogue pressure sensors have practical uses in catheter ablation and temperature sensor measurement.The answer is simple; we can use these sensors for a wide variety of control and monitoring purposes. Thanks to pressure sensors, we can accurately and conveniently measure variables such as fluid flow; water level, speed and altitude, for example. Pressure sensing is required in many different places.Conclusion:In many industries, pressure sensors are vital equipment that allows precise measurement and monitoring of pressure levels.The sensor will only take the current it needs from the power supply.Most industrial sensors are better than that, with specified accuracies of +/-0.25% or +/-0.1% of full scale (FS).A pressure sensor with a resolution of 0.1 kPa can detect and display pressure changes as small as 0.1 kilopascals. Higher resolution values indicate that the sensor can provide more precise measurements, allowing for better discrimination between different pressure level.

Light Sensor:

A light sensor is an electronic sensor that can detect the intensity of light. It can detect the intensity of light in the surrounding environment.Motion sensor lights are lights that turn on automatically when you walk by or when a car drives into the driveway. Motion sensor lights activate by movement within a specific range of the sensor. Many people place them outdoors as security lights; however, they can also be used indoors as regular light fixturesLight sensors installed as part of a lighting control system measure the amount of ambient light present and adjust the electric lights accordingly. This is known as daylight harvesting, and helps with energy efficiency by ensuring no electric light is wasted.

A sensor is a device, module, machine, or subsystem that detects events or changes in its environment and relays the information to other electronics, most commonly a computer processor. A sensor converts physical phenomena into a measurable digital signal, which can then be displayed, read, or processed further.Sensors are tools that detect and respond to some type of input from the physical environment.The simplest example of a sensor is an LDR or a Light Dependent Resistor. It is a device, whose resistance varies according to intensity of light it is subjected to. When the light falling on an LDR is more, its resistance becomes very less and when the light is less, well, the resistance of the LDR becomes very high.Sensor technology is important because it allows for the detection, measurement, and monitoring of physical, chemical, and biological phenomena in various industries such as healthcare, manufacturing, automotive, and aerospace.Sensors work by detecting physical changes in the device's environment and output them as analogue voltages or digital signals. This is then sent to a human-readable display where it can be monitored or transmitted, or relayed to other electronic devices for further processing.An ambient light sensor is a component in smartphones, notebooks, other mobile devices, automotive displays and LCD TVs. It is a photodetector that is used to sense the amount of ambient light present, and appropriately dim the device's screen to match it.Smart sensors also enable process control, such as monitoring a manufacturing process and making necessary adjustments so it can meet quality or production goals. These were once manual processes, but smart sensors have automated them. Smart sensors also play a key role in the advancement of modern security systems.

Transceiver:

A transceiver is a combination transmitter/receiver in a single package. While the term typically applies to wireless communications devices, it can also be used for transmitter/receiver devices in cable or optical fiber systems.

In radio communication, a transceiver is an electronic device which is a combination of a radio transmitter and a receiver.In radio systems, transceivers make the smooth exchange of wireless signals, enabling everything from cell phones to satellite communications. Similarly, in Ethernet networks, transceivers serve as essential interface devices, ensuring the fluid flow of data between various network components.Our mobile phones, walkie-talkie etc. are examples of transceivers. A modem is similar to a transceiver, in that it sends and receives a signal, but a modem uses modulation and demodulation. It modulates a signal being transmitted and demodulates a signal which is received.Transfer Rate. Fiber optic transceiver modules are often categorized based on their data transfer rates. There are five popular rate categories used in fiber optic transceiver classification: 100GBase, 40GBase, 10GBase, 1000Base and 100Base.Impressive Distances: High-quality transceivers can transmit signals over impressive distances, making them ideal for networks that span large areas. For example, some transceivers can transmit signals over distances of up to 80km without any signal degradation.The most common type of media converter is a device that functions as a transceiver.The old transceiver is just an adapter that took digital signals from an AUI port on one end and translated those into an electrical signal using RJ45 or some other port. Besides this transceiver type, there are several new types that will be introduced in the below part.The most common speeds for SFP transceivers are 1 Gigabit per second (Gbps) and 10 Gbps. However, there are also higher-speed options available, such as 25 Gbps, 40 Gbps, and 100 Gbps SFP transceivers. The exact maximum speed of an SFP transceiver will vary depending on the manufacturer and the specific modelNetworked Audio Transceivers can encode analog audio onto the network or decode IP audio for use with analog audio systems.It allows you to enjoy high-quality wireless audio streaming from your existing TVs and home theater systems to your Bluetooth headphones or speakers. The receiver function allows audio streaming from any Bluetooth-enabled smartphone, and it supports Qualcomm aptX Low Latency technology.

What is the proximity sensor? A proximity sensor is a non-contact sensor that detects the presence of an object (often referred to as the “target”) when the target enters the sensor's field. Depending on the type of proximity sensor, sound, light, infrared radiation (IR), or electromagnetic fields may be utilized by the sensor to detect a target.

Proximity is typically used to show a relationship between objects or a connection. It can also be used to separate different ideas or objects.Proximity sensor, a sensor able to detect the presence of nearby objects without any physical contact. Proximity space, or nearness space, in topology.The working principle of proximitors is as follows: As the shaft moves across the surface of the probe, the magnetic field is absorbed by the surface of the material. Eddy currents are formed in the shaft material, attenuating the probe coil field.For example, during a telephone call, proximity sensors play a role in detecting (and skipping) accidental touchscreen taps when mobiles are held to the ear. Proximity sensors can be used to recognise air gestures and hover-manipulations.Although every model is different, in general, the proximity sensor is located on the top of the front of the screen.Future Forecast for Proximity Sensor Industry: From 2023 to 2033, the global proximity sensor industry is anticipated to grow at a CAGR of 6.5%.

Touch sensor:

A touch sensor is a type of device that captures and records physical touch or embrace on a device and/or object. It enables a device or object to detect touch or near proximity, typically by a human user or operator.

Touch panel technologies are a key theme in current digital devices, including smartphones, slate devices like the iPad, the screens on the backs of digital cameras, the Nintendo DS, and Windows 7 devices. The term touch panel encompasses various technologies for sensing the touch of a finger or stylus.This conductive material responds when contacted by another electrical conductor, like your bare finger. When you touch your screen, an electric circuit is completed at the point where your finger makes contact, changing the electrical charge at this location. Your device registers this information as a “touch event.”Touch sensing is an input channel; touch sensing allows the computer to have greater awareness of what the user is doing with the input device. Fig. 1 Left: The TouchTrackball (a modified Kensington Expert Mouse) senses when the user touches the ball.Touch sensors are also called as tactile sensors and are sensitive to touch, force or pressure.Touch sensors are now standard in most wearables and IoT products. They are used in a wide range of display applications, from smart homes and appliances to security and industrial solutions.

The resolution of a sensor with a digital output is usually the numerical resolution of the digital output.

Electrical Sensor:

An electrical sensor (also called an electronic sensor) is a device that detects a physical parameter of interest (e.g. heat, light, sound) and converts it into electrical signal that can be measured and used by an electrical or electronic system.

What is an electrical sensor? Introduction to Electronic Sensors Electronic sensors can detect everything from light to distance to acceleration. Sensors are how a product senses anything in the real-world, and there is an almost endless array of them available. Sensors measure real-world quantities, which are then converted into an electrical signal.

Electrical sensing zone (ESZ) analysis, or the Coulter principle, is a method of characterizing particles on the submicron scale upwards.Electrical sensors are used wherever information on the state of an electrical system is needed and are employed in everything from railway systems to fan, pump, and heater monitoring.A sensor is a device that detects the change in the environment and responds to some output on the other system.A current sensor detects and measures the electric current passing through a conductor. It turns the current into a quantifiable output, such as a voltage, current, or digital signal, which may be utilised in a variety of applications for monitoring, control, or protection.Common manufacturing processes include: Semiconductor Fabrication: Many sensors, especially those based on electronic principles, are created using semiconductor fabrication processes. This involves depositing, patterning, and etching materials on a substrate to create the necessary structuresOnce you have the multimeter set to the correct setting, you'll want to place the probes on the sensor's leads. You'll want to make sure that the probes are placed on the leads in the correct order. Once the probes are in place, you'll want to check the multimeter's reading to see if the sensor is working correctly.

Chemical Sensor:

Chemical sensors are sensory receptors that detect specific chemical stimuli in the environment. The use of chemical sensors is one of the most advanced methods in analytical chemistry that makes it possible to quantitatively measure different species instantly.

The ideal chemical sensor is an inexpensive, portable, foolproof device that responds with perfect and instantaneous selectivity to a particular target chemical substance (analyte) present in any desired medium in order to produce a measurable signal output at any required analyte concentration.DEFINITIONS: A chemical sensor is a device that transforms chemical information, ranging from the concentration of a specific sample component to total composition analysis, into an analytically useful signal.One of the promises of chemical sensors is that they can be widely deployed to provide comprehensive spatial and temporal analysis of a particular problem. Such a situation has obvious benefit in the early detection of an infectious disease.

Contact sensor:

A contact sensor is a simple device made up of two components: a magnetic piece and a sensor body. The magnetic piece is attached to a door or window and the sensor body is attached to a door or window jamb. When a door or window opens, the sensor's magnetic field breaks. This break flips a switch in the sensor.

While the door/window/drawer is closed, the current flows through the mobile part, but as soon as the door/window/drawer is opened, the two pieces are separated, and the magnetic field is interrupted. The sensors detect this and raise the warning to their dedicated alarm panel.A sensor is a device that detects the change in the environment and responds to some output on the other system. A sensor converts a physical phenomenon into a measurable analog voltage (or sometimes a digital signal) converted into a human-readable display or transmitted for reading or further processing.Indicator strips (moving line, Tempadot) Liquid expansion (Mercury thermometer, Alcohol thermometer) Dial thermometers (Bimetallic strip thermometer, Bourdon gauge thermometer) FBG temperature sensors.Contact sensors are also known as touch sensors. They mainly function to detect a change in velocity, position, acceleration, torque, or force at the joints of the manipulator and the end-effector in robots. Physical contact is required for these sensors to efficiently direct the robot to act accordingly.What is a smart contact sensor?

Smoke sensor:

The short answer. Smoke alarms detect fires by sensing small particles in the air using a couple of different kinds of technologies. Once they detect those particles above a certain level, they signal the alarm to sound so that you and your family can get to safety and call 911. Smoke alarms save lives.

A smoke detector is an electronic fire-protection device that automatically senses the presence of smoke, as a key indication of fire, and sounds a warning to building occupants. Commercial and industrial smoke detectors issue a signal to a fire alarm control panel as part of a building's central fire alarm system.Area smoke detectors are generally installed in buildings and accommodation areas.An electro-optical smoke detector consists of an emitting diode and photodiode assembly which exhibits a signal under the presence of smoke.Heat detectors will directly respond to a surrounding temperature that causes the fire. These devices can set to operate rapidly and have low tolerate and respond quickly to a rapid rise in the surrounding temperature. Smoke detectors are used to detect fire based on smoke release from fire.Install a smoke sensor for every 60 square meters indoors (the specific area depends on the coverage of the smoke sensor), and install the smoke sensor 0.5-2.5 meters above the important equipment. The smoke sensor in the corridor is installed every 15 meters.Next time you change the battery in your smoke detectors, be sure to check its age, as well. According to the U.S. Fire Administration, most alarms have a life span of 8-10 years. After this time, the entire unit should be replaced. Most alarms have the date of manufacture inside the unit.What is the difference between a smoke sensor and a smoke detector? Put simply, a smoke alarm detects smoke and sounds an alarm. A smoke detector is strictly a sensing device only, which senses the products of combustion (smoke) and sends a signal to a building's fire alarm system to activate an audible, and sometimes visual warning or alarm.

Water flow sensor:

A water flow sensor, on the other hand, measures the velocity of the fluid flow at a specific point in time. It is mainly used to monitor the flow rate in real-time, to detect any changes or irregularities in the flow, and to control or regulate the flow as needed.

A water flow sensor is a specific type of flow sensor designed to measure the flow rate of water. It finds applications in various sectors, including plumbing, irrigation systems, water treatment plants, and industrial processes where water flow monitoring is crucial.A flow sensor is a component that measures the flow of a fluid such as a gas or liquid. Flow sensors utilize both mechanical and electrical subsystems to measure changes in the fluid's physical attributes and calculate its flow.Water flow meters can be used to track the flow of water within a variety of applications. They can: Measure usageby individual households or communities within municipal drinking water systems. Track sewage flowto help municipalities ensure that their wastewater systems adequately meet demand.They are commonly used in HVAC systems, medical devices, chemical factories, and septic systems. Flow sensors are able to detect leaks, blockages, pipe bursts, and changes in liquid concentration due to contamination or pollution.Example of Water Flow Sensor:YFS201 Hall effect sensor is an example of this sensor. These sensors also require a display to display the measurements. This sensor outputs 4-5 pulses for every liter of liquid flowing through it per minute. It has a working flow rate of 1-30liters per minute.Why are flow sensors important in the industry? They have many applications, such as monitoring water leakage, wastewater treatment processing, and much more. Flow meters are integral to processes that contain liquids, gases, or vapor. Without the ability to monitor fluid flow, operators are often unable to control the throughput.

Airbag Sensor:

What is an airbag sensor? The sensor is positioned inside the engine and a similar safety sensor is located inside the passenger zone of the vehicle. This safety sensor is required to measure the intensity of the collision to determine whether the impact is over a certain threshold to justify the release of an airbag

What is the description of an airbag? Airbags are inflatable cushions built into a vehicle that protect occupants from hitting the vehicle interior or objects outside the vehicle (for example, other vehicles or trees) during a collision. The instant a crash begins, sensors start to measure impact severity.Air bags are designed to keep your head, neck, and chest from slamming into the dash, steering wheel, or windshield in a front end crash. They are not designed to inflate in rear end or rollover crashes or in most side crashes.Air bags inflate when a sensor detects a front-end crash severe enough to trigger their deployment. The sensor sends an electric signal to start a chemical reaction that inflates the air bag with harmless nitrogen gas. All this happens faster than the blink of an eye.There are various types of airbags, and they are located throughout the vehicle. There are about 4 common types of airbags that a collision repair company would have to fix if they are released. These airbags are: side airbags, front airbags, knee airbags, and inflatable seat belts.Overview. Air Bag Impact Sensors detect when a crash or collision occurs. If the crash is severe enough, the sensors will send a signal to the air bag control module to deploy the air bag.There are multiple sensors on the modern airbag system and they have a long life. However the Airbag/s are pyrotechnic devices and like old fireworks might not go off very well when required. Thus they are what requires replacement at about 10 years (check handbook or a dealer.)the airbag has a low-speed deployment, usually at speeds of around 10-12 miles per hour. For belted occupants, airbags deploy at speeds of 15-17 miles per hour. In both situations, the airbag is designed to deploy when the vehicle hits the equivalent of a rigid wall.

camera:

What is a camera answer? A camera is a device that takes pictures (photographs). It uses film or electronics to make a picture of something. It is a tool of photography. A lens makes the image that the film or electronics "sees".A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film.A camera is a piece of equipment that is used for taking photographs, making films, or producing television pictures.

What are the advantages of digital camera? Advantages of Digital Cameras Instant Image Review and Feedback. Flexibility in Storage and Memory. Post-Processing Capabilities. Cost Efficiency in the Long Run. Instant Sharing and Connectivity. Wide Range of Features and Customization.

What is the disadvantage of camera? One of the main disadvantages of digital cameras is their reliance on batteries and the potential for power issues. Unlike film cameras that do not require any power source, digital cameras heavily rely on batteries to function. This means that if the batteries run out or are not charged, the camera becomes useless.Essentially, the size of the image captured is larger and of higher resolution due to the sensor within a digital camera. The shutter speeds in digital cameras are also much quicker than smartphones, meaning there is less potential blurring. But another big difference is the zoom.Are cameras good for security? Municipal Technical Advisory Service: A comprehensive look at multiple academic studies found that yes, CCTV cameras are effective in deterring crime.These controls are called ISO, aperture, and shutter speed. Photos can look wildly different based on how you adjust these controls. Most phone cameras automatically adjust these controls to result in a well exposed image but you loose the ability to get exactly the kind of image you want.How a camera works?the light entering through the lens strikes an image sensor. The signal output by the image sensor is processed within the camera to create image data, which is stored on the memory card. The image can be simultaneously viewed on the picture display. Why is the camera important? The importance of photography in our modern times It allows us to capture and preserve memories, connect with others, and document history. Whether you're a professional photographer or an amateur, taking photos can be a great way to capture and share your experiences with the world.
