How does an infrared proximity sensor work

A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximi… WebApr 1, 2024 · Infrared proximity sensors consist of an IR LED that emits, and a light detector for detection of reflection. It has an in-built signal processing circuit that determines an optical spot on the PSD. Working Principle Infrared light is emitted from the IR LED emitter The beam of light hits the object and gets reflected back in an angle
