Introduction: Wiring the Diffused Reflection Laser Sensor With Arduino Microcontroller

About: something about yourself so our community can get to know you! ??

This is a diffused reflection laser sensor that has an integrated IR transmitter and a receiver. This sensor using light that transmit by the Laser and receive by the Infrared since the laser adopts modulation processing technology, the receiving tube can only receive the reflected light in the same frequency. Laser Sensor can detect obstacles at 0.8m (typ), 1.5m (max) the sensor has an oscillating tube that can generate a shock-wave in a frequency of 180 KHz. This sensor can be used to obstacle detection, counter devices at the pipeline, robotics, and smarts car, etc.
