Optical rain gauge
In fields such as meteorological monitoring, urban flood control, smart agriculture, and geological disaster early warning, the continuity and reliability of precipitation data are crucial for decision-making. Optical rain gauges , as a new generation of precipitation monitoring equipment, rely on non-contact optical sensing technology, overcoming the limitations of traditional mechanical rain gauges and becoming a key terminal in environmental monitoring systems. The Value and Importance of Optical Rain Gauges Precipitation monitoring is a fundamental aspect of meteorological observation. Traditional tipping bucket and siphon rain gauges rely on mechanical structures, which are prone to wear, clogging, and jamming with long-term use. Data deviations are particularly pronounced in complex environments such as heavy rain, freezing rain, and dust storms, and maintenance costs are high. Optical rain gauges detect precipitation through infrared light scattering or blocking principles,...
