SEM7000 Ultrasonic Meteorological And Environmental Weather Station

The SEM7000 Ultrasonic Meteorological And Environmental Weather Station is a compact, next-generation meteorological station that utilizes ultrasonic sensors to measure wind speed and direction. Featuring an integrated design with no moving parts, it offers high precision, immunity to mechanical wear, and a low failure rate. Capable of 2D wind measurement and featuring a compact footprint, it serves as a complete replacement for traditional weather stations.

The SEM7000 multi-parameter micro-meteorological monitor integrates data acquisition, storage, transmission, and management. It captures real-time meteorological data—including ambient temperature, humidity, wind speed, wind direction, atmospheric pressure, rainfall, and solar radiation—and transmits this information to a remote monitoring center or video surveillance equipment (for secondary integration) via RS485, Wi-Fi, GPRS, or 4G networks. In the event of an anomaly, the system issues alerts through multiple channels, prompting management personnel to address the issue or take necessary corrective actions.
