10 x Infrared Obstacle Avoidance Module
Module interface description
1 - VCC external 3.3V-5V voltage (can be directly connected to 5v microcontroller and 3.3v microcontroller)
2 - GND External GND
3 - OUT small board digital output interface (0 and 1)
Low interference, easy assembly, easy to use.
The detection distance can be adjusted by the potentiometer, the potentiometer is adjusted clockwise, the detection distance is increased the potentiometer is adjusted counterclockwise, and the detection distance is reduced.
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 the large area distance is large.
The sensor module output port OUT can be directly connected to the MCU IO port, or can directly drive a 5V relay, connection mode: VCC-VCC; GND-GND; OUT-IO.
Each module has adjusted the threshold comparison voltage through the potentiometer during shipment. For non-special cases, do not adjust the potentiometer at will.
