[0002] Precipitation refers to the depth of liquid or solid (after melting) water that falls from the sky to the ground and accumulates on the horizontal surface without evaporation, infiltration or loss. Precipitation is measured in mm, and one decimal place is taken in meteorological observation, which can intuitively indicate the amount of rainfall.

In addition, during popular science, water is generally poured into the rain gauge manually, which makes it difficult to simulate different rainfall amounts, and it does not have a rainfall display function, making the popular science experience effect unsatisfactory.
