2、 Function Description
The rainfall sensor is composed of a water receiver, an upper tipping bucket, a metering tipping bucket, a counting tipping bucket, etc. Its working process is: rainwater is collected by the water receiver and enters the upper tipping bucket. The function of the upper tipping bucket is to divert precipitation and then enter the metering tipping bucket. The metering tipping bucket flips once for 0 1mm precipitation. Subsequently, the rainwater is poured from the metering bucket into the counting bucket. The counting flip bucket rotates once, and the dry spring switch in the middle of the counting flip bucket is closed once under the action of the small magnetic steel, so that the microcontroller can receive a signal.
