overview
Arduino infared proximity switch module is a reflection-type photoelectric sensor which integrates transmitting and receiving infared beams function. 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 there is an object nearby.
