Welcome to Infrared module repository
Introduction of Infrared module
1. Working principle
The basic principle of the infrared sensor is to use the reflective nature of the object. Within a certain range, if there is an obstacle, the infrared rays will encounter obstacle and will be reflected to reach the sensor receiving pin.
After processing, the signal is returned to the micro-controller through the digital sensor interface, and the micro-controller can use the return signal to identify changes in the surrounding environment.
2.1 Infrared avoid or infrared follow
2.2 As human detection
3.1 Infrared module possess 4 Alligator clip port, Corresponding to GND, VCC, NC and OUT. OUT pin is the signal output pins of the module.
3.2 4 pin female socket.
3.3 PH2.0 cable interface.
It can detect if there are obstacles.
Working Voltage: 3.3V/5V
