IR Sensor Digital Single Array Line 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 onboard preset helps to fine-tune the range of operation, the effective distance range is 2 cm to 30 cm.Infrared Obstacle Avoidance IR Sensor Module
