Voltage: 5V
power indicator, output signal LED. 
TTL level output, TTL output valid signal is low. Drive capacity of about 100MA, can directly drive the relay, buzzer, small fan, and so on. 
Sensitivity can be adjusted by the potentiometer
No rain when the LED light up the output is high, raindrops up, the output level, LED light. 
The razor board and the control board are separate to facilitate the thread leads. 
Large area of ​​rainboard, more conducive to the detection of rain. 
Board with a positioning hole to
facilitate the installation of control board board size: 3 * 1.6 CM
large area raindrops detection board 5.4 * 4.0 CM

How to Use:
connected to the 5V power supply light, the sensor board is no water droplets, DO output is high, the switch indicator off, drop a drop of water, DO output is low, the switch indicator light,
brush off the above water droplets , And then return to the output high state. The The The 
AO analog output, you can connect the microcontroller's AD port to detect the amount of rainfall in the above. 
DO TTL digital output can also be connected to the microcontroller to detect whether there is rain.
