Introduction
Infrared break-beam sensors are a simple way to detect motion.
This IR break beam sensor works up to 50cm with a fast and stable response of 2ms. With a small size of 20*10*9mm, the module can be conveniently installed in a narrow space. Besides, it can operate within a temperature of -25C to 60C.
Power the sensor by a voltage of DC 3.0~5V. It can be used with Arduino for some simple motion detection, speed detection, timing, etc. in smart robot competitions.
They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between the two, and its not transparent to IR, then thebeam is brokenand the receiver will output a signal to let you know.
