Obstacle Avoidance Sensor Module, When the module detects an obstacle in front of the signal , the circuit board green indicator light levels while continuing output low signal OUT port , the module detects the distance 2 ~ 60cm, detection angle 35 °, the distance can detect potential control to adjust, adjust potentiometer clockwise , the detection distance increases ; counterclockwise adjustment potentiometer, detection distance decreases.
3-5V DC power supply for the module . When the power is turned on, the red power indicator light ;
Circuit board size : 3.1CM * 1.5CM
module interface specification ( 3-wire )
