Photo Interrupter Sensor

A photo-interrupter sensor detects when something blocks the light between the infrared emitter and receiver elements. They're great for robot projects, item dispensing, object detection and more - use them however you like! This sensor features an indicator LED to show you when the beam has detected an object - great for debugging. The sensor also comes with a 20-slot encoder disk and a 3-pin XH2.54 cable. Features

* Infrared detection, eliminating the interferences of external stray light

* Schmitt trigger - stable waveform and signals

* Signal output indicator (while breaking the beam the sensor outputs a low level and the indicator LED lights up)
