Features:

When connected to a 5V power supply , power indicator light, no water droplets on-board sensors , DO output is high, switch lights off, drop a drop of water , DO output is low, the switch indicator light,

Brush above water droplets, has returned to output high state. . . .

AO analog output can be connected to the microcontroller AD port to detect drops in the above rainfall size.

DO TTL digital outputs can also be connected to the microcontroller to detect whether there is rain .

Connection:

 VCC: positive power supply (3-5V)

 GND: power supply is negative

 DO: TTL switching signal output

 AO: analog signal output

Package included:

1 x raindrops module

4 x female to female cable
