When the module detects the front obstacle signal, the green light on the circuit board lights up the level, while the OUT port continuously outputs the low level signal, the module detection distance is 2 to 30cm, the detection angle is 35 degrees, the detection distance can be adjusted by the potential device, clockwise adjust the potential device, the detection distance increases;
sensor active infrared reflection detection, so the target's reflectivity and shape is the key to the detction distance. Among them, the black detection distance is the smallest and the white is the largest; Small area object distance is small, large area distance is large.
the sensor module output port OUT can be directly connected with the microcontroller IO port, can also directly drive a 5V relay; GND-GND;OUT-IO
comparator using LM393, stable work;
can use 3-5V DC power supply to power the module. When the power is on, the red power LED lights up;
with 3mm screw holes, easy to fix, installation;
board size: 3.2CM x 1.4C
each module in the hipment has been the threshold comparison voltage through the potential device adjustment, non-special circumstances, do not adjust the potential device at will.
Module interface description
VCC external 3.3V-5V voltage (can be directly connected to 5v microcontroller and 3.3v microcontroller)
GND external GND
OUT small board digital output interface (0 and 1)
