Infrared obstacle / Avoidance Sensor is an ambient light sensor adaptable can be place on your wheeled robots for obstacle avoidance or distance sensor. This sensor has a high precision components paired of infrared transmitter and receiver. The transmitter tubes emit a certain frequency of infrared when detecting a direction or obstacle or a reflector the infrared receiver tube receive a reflected signal came from the obstacle then the indicator output will turn to HIGH as you can see at the board there are two type of trimmer or potentiometer knob to adjust the distance from 2 to 40 cm. running at 3.3v or 5v dc.
