Connected to 5 v power supply, power indicator, no water droplets on induction plate, the DO output high level, switch indicator light out, drop a drop of water on, the DO output for the low level, the switch light is lit,Brush away the water droplets, again to return to, the output high level... AO analog output, which can be connected to the microcontroller AD mouth detection drops of rainfall in the above size. DO TTL digital output also can connect to the single chip microcomputer detect whether there is rain
