Infrared Light - an overview | ScienceDirect Topics

Infrared (IR) is a form of electromagnetic radiation same as that of radio waves, UV light rays, visible light, X-rays, and gamma rays. All of these are forms of electromagnetic waves that travel at the speed of light. The wavelength range of visible light ranges from 390 to 750 nm, while infrared ranges from to 1000 μm much longer than that of the light in the visible spectrum [125 ...

Basics of IR Sensor | IR LED Pin Diagram & Working

· The IR rays from the IR LED in the circuit are shown in the camera. Pin Diagram of IR LED. An IR LED is a type of diode or simple semiconductor. Electric current is allowed to flow in only one direction in diodes. As the current flows, electrons fall from one part of the diode into holes on another part. In order to fall into these holes, the electrons must shed energy in the form of photons ...

What's the difference between IR and RF? | Bond

RF uses radio waves and IR is a kind of light that can’t be seen with the naked eye. A good many consumers, when holding a remote control, may not know which kind is in his or her hand. As long as it works, few people care. But if you’re curious, the easiest way to tell is if you need to point the remote directly at the device you’re trying to control. Your TV remote is IR.

IR Sensor : Circuit Diagram, Types Working with Applications

In this project, the transmitter section includes an IR sensor, which transmits continuous IR rays to be received by an IR receiver module. An IR output terminal of the receiver varies depending upon its receiving of IR rays. Since this variation cannot be analyzed as such, therefore this output can be fed to a comparator circuit. Here an operational amplifier (op-amp) of LM 339 is used as a ...
