IR Sensor, Obstacle Avoider Sensor

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 30cm. It can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and black and white line tracking.
