IR Infrared Obstacle Avoidance Sensor Module has a pair of infrared transmitting and receiving tubes. When the light waves transmitted from the IR transmitter and reflected back, the reflected IR waves are then received by the receiver. The onboard comparator circuitry does the processing and the green indicator LED comes to life.
This Infrared Proximity Sensor module features a 3 wire interface with Vcc, GND and an OUTPUT pin on its tail. It works fine with 3.3 to 5V levels. Upon hindrance/reflectance, the output pin gives out a digital signal (a low-level signal). The onboard preset helps to fine-tune the range of operation, effective distance range is 2cm to 80cm.
