[0002] Commonly monitored elements in the environment include temperature and humidity, wind speed and direction, rainfall, atmospheric pollutants, etc. Changes in these meteorological factors will have an impact on people's production and life. Among them, rainfall is one of the common weather phenomena in nature. It refers to the process in which condensed water vapor in the atmosphere falls to the ground in different ways. The monitoring of rainfall has a certain guiding role in agricultural irrigation, so as to formulate reasonable irrigation measures; the rain gauge can monitor rainfall information, report weather conditions in a timely manner, and remind people to pay attention to road conditions and make rain prevention preparations when traveling.

Rain gauges are needed in the process of monitoring rainfall. General weighing rain gauges are often installed outdoors, but in the complex outdoor environment, when there is no rainfall, strong winds and heavy snow will cause certain damage risks to the rain gauge itself.
