Description
**Rain Detection Module**
Ability to drive about 100 mA, can be directly driven relay, buzzer, and so on.
Sensitivity can be adjusted through the potentiometer
No rain when the LED light output for the high level, rain, and the output level, the LED light.
Raindrops board and control board are separated, convenient to wire leads.
The raindrops plates of large area, more conducive to detect the rain.
The board with a hole, convenient installation
- Voltage: 5v
- LED lamp power light, the output signal.
- TTL level output, and Analogic level.
