Decription:
Description:
1. 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 potentiometer is adjusted, the potentiometer is adjusted clockwise, the detection distance is increased, and the potentiometer is adjusted counterclockwise to reduce the detection distance.
2. The sensor actively detects infrared reflections, so the reflectivity and shape of the target are the key to detecting the 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.
3. 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
4. The comparator uses LM393 and works stably;
5. The module can be powered by a 3-5V DC power supply. When the power is turned on, the red power indicator lights up;
6. With 3mm screw holes for easy fixing and installation;
7. Board size: 3.2CM*1.4CM
Interface Description (3-wire):
1. VCC: external 3.3V-5V voltage (can be directly connected to 5v MCU and 3.3v MCU)
2. GND: GND External
3. OUT: small board digital output interfaces (0 and 1)
Included:
1 x IR Infrared Obstacle Sensor Module
