1PCS Smart Car Robot Reflective Photoelectric 3pin IR Infrared Obstacle Avoidance Sensor Module

Type:Gas Sensor Material:Mixture Usage:Infrared obstacle avoidance The detection range is 2 ~ 30cm and the detection angle is 35 °. The detection distance can be set by the potential Adjust the device, clockwise adjust the potentiometer, detection distance increases; counterclockwise adjustment potentiometer, detection distance decreases. the sensor active infrared reflection detection, so the target reflectivity and shape of the key is to detect the distance. Among them, the black detection distance is the smallest and the white is the largest. Connection: VCC-VCC; GND-GND; OUT-IO 3-5V DC power supply can be used to power the module. When the power is on, the red power indicator light with 3mm screw hole, easy to fix, install the circuit board size: 3.2CM×1.4CM
