How to Use

In the case of working with a MCU:

  • VCC ↔ 2.5V ~ 5.0V
  • GND ↔ power supply ground
  • DOUT ↔ MCU.IO (digital output)

Operating principle

A laser sensor contains a transmitter and a receiver.In the transmitter, there is an oscillating tube can generate a shockwave in a frequency of 180 KHz. After amplified by a transistor, the shockwave is applied to the laser tube for exciting.In the receiver, there is a receiving tube, matching to the oscillating tube,can receive the reflected light. Since the laser sensor adopts modulation processing technology, the receiving tube can only receive the reflected light in a same frequency, efficiently preventing from the visible light.
