Working principle of weather instruments rain sensor

Rain sensor

The rainfall sensor measures the rainfall at a certain time and a certain place. Weather instruments that convert rainfall into rainfall measured by physical signals. Rainfall sensors include various forms such as single tipping bucket, double tipping bucket, and multiple tipping buckets. It is suitable for matching various large and small weather stations, hydrological stations, agriculture, environmental protection, forestry and other related testing departments. Provide original data for flood control, water supply dispatching, and water regime management of power station and reservoir.

Working principle of rain sensor

The rain sensor is the sensor’s reservoir to collect rainwater and enter the upper tipping bucket through the funnel. When the rainfall accumulates to a certain amount. Due to the gravity of the water itself, the upper tipping bucket is turned over. The water enters the collecting funnel. When rainwater is injected into the tipping bucket from the throttling tube of the confluence funnel. Adjust the natural rainfall of different intensities to a relatively uniform intensity of heavy rainfall. In order to reduce the measurement error caused by different rainfall intensities.

When the rainfall during storage and reception of the measuring hopper is 0.1mm. The metering bucket of the rain sensor dumps the rainfall to the metering bucket. Turn the metering bucket once. once. Calculated when the tipping bucket tipped over. The scanning tube of the magnet pair related to the magnetization will be closed immediately. The scanning tube of the relevant magnet pair will be shut down immediately due to magnetization. In this way, every time the rain comes. The rain sensor will send out a signal.

Advantages of rain sensor

Rainfall sensor independently researched and developed rain-bearing openings are fully in line with national standards. It uses ABS engineering plastics.The smoothness is small and the error caused by stagnant water is small. Various output methods such as rs485/analog, 4G, NB-IOT and LORA are available for your choice, which can better meet different needs. Used to measure rainfall in nature. At the same time, the rainfall is converted into digital information output in the form of on-off value. To meet the needs of information transmission, processing, recording and display. Factory direct sales, the price is more close to the people.quality assurance. Exquisite materials. People use it more at ease.
