Yahboom Infrared Module for Microbit Ranging and Obstacle Avoidance Patrol

Introduction of Infrared module1 Working principleThe basic principle of infrared sensors is to use the reflective properties of objects Within a certain range if there is an obstacle infrared rays will meet the obstacle and 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 Practical application2 1 Infrared avoid or infrared follow2 2 As human detection 3 About module3 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 Package Included 1 x Infrared Module
