SEN0381

SEN0381 Digital IR Proximity Sensor

DFRobot SEN0381 Digital IR Proximity Sensor provides adjustable distance detection within 0 to 200cm and comes with real-time status feedback. This sensor works on the principle of diffuse-reflection of IR-light on objects and is able to auto-detect and save the distance between itself and obstacles ahead. The SEN0381 digital IR proximity sensor is equipped with a 3-pin data cable (digital signal output) that can be directly plugged into an Arduino IO expansion board. This sensor device can be widely used in applications like smart homes, house security, intelligent detection and control, and robot obstacles.
