An Infrared sensor is an electronic device that emits radiation to sense some objects of the surrondings. This device can be used to detect heat as well as motion of the objects that surronds it. Some IR sensors can only measure infrared radiation rather than the emission, such type of sensor is known as passive infrared sensor. All the objects that present in the environment emits some form of thermal radiations but generally they will not be visible to human eyes. IR sensors makes use of such radiations to detect their presence.

The emitter is simply an IR LED (Light Emitting Diode) and the detector is simply an IR photodiode which is sensitive to IR light of the same wavelength as that emitted by the IR LED. The resistances and output voltages changes in accordance to the magnitude of the IR light received
