Smart Electronics Smart Car Robot Reflective Photoelectric 3pin IR Infrared Obstacle Avoidance Sensor Module for arduino Diy Kit

• 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 ~ 30cm, detection angle 35 , the distance can detect potential control to adjust, adjust potentiometer clockwise, the detection distance increases; counterclockwise adjustment potentiometer, detection distance decreases.
• The sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The minimum detection distance which black and white max; small area of the object distance is small, a large area from the Grand.
• The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO
• The comparator using LM393, job stability;
• Can be 3-5V DC power supply for the module. When the power is turned on, the red power indicator light;
• With 3mm screw holes for easy mounting, installation;
• The circuit board size: 3.2CM * 1.4CM
• Each module in the delivery has threshold comparator voltage adjustable via potentiometer, special circumstances, please do not adjust the potentiometer.
