The emitting part of the laser sensor is a 180KHz oscillator emitted by an oscillator tube, amplified by a triode, the laser tube emits light, and the receiving part receives the returned light intensity from a matching 180KHz receiver tube. Since the laser sensor uses modulation processing, the receiving tube can only accept the reflected light of the same frequency, so the influence of visible light on the reflected laser can be effectively prevented.
Applications
- Obstacle detection
- Pipeline counter
- Smart robot
- Obstacle-avoiding car
Pinouts
In the case of working with an MCU:
- VCC ↔ 3.3V (be aware of this)
- GND ↔ Power Supply Ground
- DOUT ↔ MCU.IO (digital output)
