RAINFALL SENSOR

RY-YLH02

MANUAL

INTRODUCTION & PRINCIPLE

The RY-YLH02 rainfall sensor is used to measure ground rainfall. It can be widely used in small weather stations, hydrological stations, agriculture and forestry and other related departments to measure precipitation, precipitation intensity, and precipitation time.

Rain flows into the dump bucket through a receiver. When a certain amount of rainwater flows into the dump bucket, the dump bucket flips over, emptying the rain in the dump bucket, and the dump bucket starts to receive water again. Each reversing action of the dump bucket is converted into a pulse signal by a reed switch ( 1 pulse = 0.2mm precipitation) to the acquisition system. This instrument is suitable for equipping national basic rainfall stations, encrypted automatic meteorology (rainfall stations) and telemetry stations in various places and under different climatic conditions to complete the automatic measurement and data collection of the precipitation process. The device consists of a bucket, a black bucket, a control circuit board, a floor box, a chassis, a right-angle fixing bracket (1), and a right-angle mounting bracket (2).
