Adopting a solution combine radar and video, which can warn flood automatically and accurately. Millimeter wave radar senses changes in water level accurately. The video AI algorithm identifies foreign objects on the water surface intelligently, so as to prevent false alarms of abnormal water levels.Adopting modular design, multiple meteorological sensors and solar power supply systems can be easily expanded, forming a small hydrological workstation suitable for multi-purpose scenarios.Adopting a geometric design language, the appearance is simple and atmospheric, perfectly integrated with the usage environment
