Applications

Radar rain gauge sensor applications Tips: How is the accuracy of the radar rain gauge sensor assured?

The radar rain gauge sensor utilizes high-precision radar technology to accurately monitor the speed and volume of raindrops in order to calculate the amount of rainfall. The device's built-in auto-calibration system regularly adjusts the radar rain gauge sensor's measurement parameters to ensure the accuracy of the data. In addition, the rainfall sensor has a strong anti-interference capability and can work stably even in bad weather, greatly reducing data errors. For particularly delicate rainfall monitoring needs, please ensure that the installation location is suitable to avoid interference of radar signals by environmental obstacles.
