When the module detects obstacles in front of signal, green indicator light, and "OUT" port sustained transfer low-level signals. Detects distance of this module is 2 to 60cm, detection angle of 35 , the detection distance can adjustedby potentiometer, adjust the potentiometer clockwise, the detection distance increases; counterclockwise adjusts the potentiometer, the detection distance is reduced.
The sensor active infrared reflectance probe, therefore, the reflectance and the shape of the target is the key of the detection distance. For detection range, Black is the smallest, white is the largest. Small object, distance is small, a large Object, distance is large.
The sensor module output port OUT can be directly connected with the single-chip IO, and also can directly drive a 5V relay; Connection as: VCC-VCC; GND-GND; OUT-IO
Use LM393, work stability;
3-5V DC power supply, when the power is turned on, the red power indicator lights;
With a 3mm screw holes, easy fixed installation;
