IR Sensor Module – LM393 Photoelectric Sensor Module

Photoelectric sensor module is a sensor module which you can use to identify the distance between obstacles, identifying changes in surroundings etc. applications. It has an IR transmitter, IR Receiver, LM393 and a potentiometer to set a threshold for digital output. When light brightness of ambient is less than the set threshold, DO-side output is high, when light brightness of ambient is over the threshold, DO-ended output is low. This module can be used in obstacle detection in autonomous robots and cars, in positional feedback for control system, industrial safety system, Wheel encoder etc.
