High Sensitivity Rain Sensor -Arduino Compatible

High Sensitivity Rain Sensor -Arduino Compatible

Feature:
1. Voltage: 5V
2. Power indicator light, the output signal LED indicating lamp
3. TTL level output, TTL output signal for low level drive capacity of around 100MA, can directly drive the relay, a buzzer, a small fan, etc..
4. Sensitivity adjustment via potentiometer
5. No rain when the LED light output is high, the output level, go up, LED bright
6. The board and the control board is separate, convenient wire
7. A large area of the board, more conducive to detect the rain
8. The board is equipped with a positioning hole to facilitate installation
9. Control panel board size: 3*1.6 MM
10. A large area of raindrop detection board 5.4*4.0 MM
11. Connect cable: 200MM

Using the two methods:
Connected to 5V power supply lights, induction board did not drop, DO output is high, the switch indication lamp is off, drop a drop of water, DO output is low, the switch indicator lights
Brush off the water droplets, and restored to the state, output high level....
Analog AO output, can be connected to the MCU AD port detection of drops in the above amount of rainfall
DO TTL digital output can also be connected with the singlechip detects whether there is rain

Package includes:
1 x weather module
