1, When the module detects obstacles in front of the signal, the green LED is lit on the board level, while continuing OUT port outputs a low level signal, the module detection distance 2 ~ 30cm, detection angle 35 °, the detection distance by potentiometer was adjusted, adjust potentiometer clockwise, to increase the detection distance; counterclockwise to adjust potentiometer, reduce the detection distance.2, the sensor active infrared reflection detection, so the target reflectivity and shape is the key to the detection distance. Wherein the black detection range minimum, maximum white; small area of small objects from a large area from the great.3, the sensor module output port OUT port can be directly connected to the microcontroller IO, can directly drive a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO4, comparators LM393, stable;5, can be used for 3-5V DC power supply module. When the power is turned on, the red power indicator lights;6, with screw holes 3mm, easy fixed installation;7, circuit board size: 3.2CM * 1.4CM8, each module has been shipped threshold comparator voltage adjustable by potentiometer good, non-special case, do not adjustable potentiometer.circuit board size: 3.2CM * 1.4CM
