Infrared Obstacle Sensor Module has a built-in IR transmitter and IR receiver that sends out IR energy and looks for reflected IR energy to detect the presence of any obstacle in front of the sensor module. The module has an onboard potentiometer that lets users adjust the detection range. The sensor has a very good and stable response even in ambient light or in complete darkness. The module has an effective distance range 2 ~ 80 cm The sensor module light is adaptable to the environment, Specifications : Working Voltage : 3.3v to 5v Detectable Distance : 2 ~ 30cm, Detection angle : 35 ° Comparator chip: LM393 Adjustable detection distance range via potentiometer Clockwise : Increase detection distance Counter-clockwise : Reduce detection distance
