A large area of raindrop detection board 5.4*4.0 MM
The method of usage
Connected to 5V power supply, the light will bright, when induction board has not rain drop, DO output is high, and the switch indication lamp is off, when dropping a little water, DO output is low, the switch indicator will bright
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 also can be connected with the MCU to detect whether there is rain.
