The RF rain gauge is a hydrological, meteorological and environmental monitoring instrument used to measure the rainfall in nature. Its principle is that the rotation of the rain gauge's tipping bucket generates on-off pulse signals in its components. The collection terminal acquires the generated pulse signals and calculates and converts them into precise rainfall data. This product features a high degree of automation, strong timeliness in obtaining precipitation, and the rainfall data is easy to save and transmit. In addition, it features strong anti-interference ability, all-outdoor design, high precision of the measuring machine, fully automatic unattended operation, and stable operation. It is particularly suitable for automatic rainfall monitoring stations in the wild
