This is an Infrared Barrier Module that can be used with any microcontroller unit. When the module detects obstacles in front of signal transmitted by IR LED, green indicator light goes ON, and “OUT” port sustains transfers low-level signals. Detection distance of this module is 2 to 60cm, detection angle of 35 °, the detection distance can adjusted by potentiometer, adjust the potentiometer clockwise, the detection distance increases; counter-clockwise adjusts the potentiometer, the detection distance is reduced.
Module interface specification:
- VCC: 3v-12v power supply(can directly connect to 5v or 3.3v microcontroller)
- GND: Connect GND
- OUT: board digital output interface (0 and 1)
