Arduino infrared proximity switch module is a reflection-type photoelectric sensor which integrates transmitting and receiving infrared beams. Infrared proximity switches work by sending out beams of invisible infrared light. A photodetector on the proximity switch detects any reflections of this light. These reflections allow infrared proximity switches to determine whether or not there is an object nearby.
