Rain ＆ Snow Sensor

Tipping bucket rain gauge, rainwater enters the water receiver from the water receiving port, falls into the water receiving funnel, and flows into the tipping bucket through the funnel mouth. When the accumulated water reaches a certain height (such as 0.01 mm), the tipping bucket loses balance and overturns. And every time the tipping bucket tips over, the switch connects the circuit and sends a pulse signal to the recorder. The recorder controls the self-recording pen to record the rainfall, and so on. The rainfall is measured by recording the number of pulses.

Radar rain gauge, using flat radar module, uses 24GHz Doppler radar wave technology to measure the falling speed of water droplets during rainfall, and distinguishes the type of rain, snow and hail, as well as the intensity of rainfall according to the droplet size and falling speed. Radar rainfall detection is more sensitive than mechanical rainfall detection methods, and can detect the start and end time of rainfall more quickly.

Piezoelectric rain gauge uses piezoelectric sensor module to measure the intensity of rainfall based on the voltage effect generated by the impact of raindrops on the piezoelectric module. The piezoelectric effect is used to convert mechanical displacement into electrical signals, and the amount of rainfall is obtained based on the change in voltage waveform converted from the energy of raindrop impact, thereby realizing the measurement of the weight of a single raindrop and then calculating the rainfall. Piezoelectric rain gauge has no mechanical accessories, so it is more durable, sensitive and reliable than rain gauges of other technologies, maintenance-free, and does not require on-site calibration.

Road condition sensor, based on multispectral remote sensing technology, non-contact real-time monitoring of road ice, snow and water thickness. Remote sensing technology, no need to close the road or cut the road surface during installation, installation work is safe and convenient. Low maintenance, it is an ideal choice for road weather monitoring. The sensor is installed in an all-weather, durable housing to ensure accurate data even in adverse weather conditions.

Weighing evaporation sensor (pressure evaporation sensor) uses high-precision weighing principle to measure the weight of the liquid in the evaporating dish, and then calculates the liquid level. It can be used in a variety of environments, such as liquid or ice. The weighing evaporation water level sensor solves the drawbacks of using the ultrasonic principle to measure the liquid level (such as inaccurate measurement when iced, easy damage to the sensor when there is no water, etc.).

The rain and snow sensor is based on the principle of liquid conductivity. It uses electrodes to detect whether there is water. It is used for qualitative measurement of whether it is raining or snowing outdoors. The rain and snow sensor can be used directly for monitoring in rainy climates; when snowing occurs, the sensor will be heated to 40°C to melt the snow into water for monitoring.
