Rain recorder

The rain recorder includes a host, a rain sensor. When using, the host and the rainfall sensor should be connected first, and then placed on the monitoring point, and the host should be turned on to record the measured rainfall data. The measured and recorded rainfall information is helpful to People's Daily production and life.

As a hydrometeorological instrument, the rain recorder measures the rainfall in nature, and at the same time converts the rainfall into a switch quantity output digital information, so as to meet the requirements of information transmission, processing, recording and display.

Why do people measure rain? When the sun is fine and the grain is full, the cattle and sheep are in herds. But storms and other floods have left people hungry and cold and forced them to leave their homes. This experience made people deeply feel the impact of rainstorms and other flooding weather on their lives, and began to pay attention to changes in the weather. In order to avoid the occurrence of natural disasters in advance, humans adopted primitive methods to measure rainfall, understand the weather and accumulate experience.

As far as agricultural production is concerned, the issue of rainfall is crucial for local agricultural meteorology. People can grasp the local drought situation and guide water resource management from the data of rainfall and soil moisture. At the same time, they can use rain recorders and other instruments to guide local irrigation. Therefore, the rain recorder is not only used in modern agricultural research and teaching, but also in agricultural meteorology, facility agriculture, precision agriculture has been widely used.
