Wiring Light Blocking / Photo Interrupter Sensor

Another guide from 37 in 1 sensor, in this illustration we will going to wire the light interrupter sensor or photo interrupter. A photo Interrupter is transmission type photo sensor that integrates optical receiving and transmitting elements in a single package please see the diagram below. Since the method involves light blocking commonly named photo interrupter. A long life infrared photo diodes is applied for output while a single photo transistor and photo IC are integrated on the other side for light detection.
