Product description
Specification:
– When the module detects the obstacle signal in front the green indicator on the board lights up and the OUT port continuously outputs a low level signal. The detection distance of the module is 2~30cm the detection angle is 35° and the detection distance can pass the potential. Adjust the device adjust the potentiometer clockwise increase the detection distance; adjust the potentiometer counterclockwise to reduce the detection distance.
– the sensor active infrared reflection detection so the target’s reflectivity and shape is the key to the detection distance. Among them the black detection distance is the smallest and the white is the largest; the small-area object has a small distance and a large area has a large distance.
– The sensor module output port OUT can be directly connected to the IO port of the MCU or it can directly drive a 5V relay; connection mode: VCC-VCC; GND-GND; OUT-IO
– the comparator uses LM393 the work is stable;
– The module can be powered by 3-5V DC power supply. When the power is turned on the red power indicator lights up;
– with 3mm screw holes for easy fixing and installation;
– circuit board size: 3.2CM * 1.4CM
8. Each module has adjusted the threshold voltage to the potentiometer through the potentiometer. For non- special cases do not adjust the potentiometer at will.
Module interface:
– 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)
