IR Infrared Obstacle Avoidance Sensor Module For Arduino Smart Car Robot 3-Wire

About IR Infrared Obstacle Avoidance Sensor Module For Arduino Smart Car Robot 3-Wire

Description:

IR Infrared Obstacle Avoidance Sensor Module has a pair of infrared transmitting and receiving tubes. When the transmitted light waves are reflected back, the reflected IR waves will be received by the receiver tube. The on-board comparator circuitry does the processing and the green indicator LED comes to life. The 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 on-board preset helps to fine tune the range of operation, effective distance range is 2cm to 80cm.
