Flood season is here, these rain sensors come in handy

The season of frequent rainfall is accompanied by a corresponding increase in the risk of urban and rural flooding, flash floods, geological disasters and river flooding. During the rainy season, it is critical to accurately monitor rainfall, safeguard infrastructure, rationally plan agricultural irrigation and prevent flooding. Fengtu Technology provides the following sensors, which can provide you with effective rainy season monitoring solutions.

1.Tipping bucket rainfall sensor

Windway's brand of tipping bucket rainfall recorder is a specialised device for determining the amount of rainfall. It works by using raindrops falling on a receiver, which is mechanically tilted over to convert changes in rainfall into electrical signals that can be measured and recorded. This design allows the tipping bucket rain gauge to accurately capture and record rainfall, providing reliable data for meteorological monitoring and hydrological research.

2. Piezoelectric Rain Sensor

Fengtu's piezoelectric rain sensor uses advanced piezoelectric effect technology to accurately measure rainfall. Compared with the traditional tipping bucket rain gauge, it has the advantage of having no moving parts, thus providing a quicker response and more sensitive sensing of rainfall. This design not only improves the accuracy of the measurement, but also increases the durability and reliability of the device.

3. Radar Rainfall Sensor

This device is equipped with a small flat panel radar component inside, utilising 24GHz Doppler radar technology. It analyses the rate at which raindrops fall to differentiate the size of raindrops as well as to identify different precipitation patterns such as rain, snow and hail. Using this data, combined with statistical methods and mathematical models, the sensor is able to simulate and calculate the total amount of rainfall over a given period of time.

4.Optical Rainfall Sensor

Based on the optical sensing principle, it is built-in with multiple high-precision optical probes to achieve accurate detection of rainfall. It abandons the traditional mechanical sensor approach and provides a smaller, more sensitive and smarter solution, while simplifying the maintenance process and improving the stability and service life of the equipment.

These sensors are able to monitor rainfall in real time, assess waterlogging, provide timely warnings of possible flooding and geological hazards, and help relevant authorities and individuals take preventive measures. Through accurate data collection and analysis, they provide a scientific basis for decision-making in agricultural irrigation, optimising the use of water resources and reducing damage caused by flooding.
