AWS1900 is a professional nine-parameter automatic weather station. It integrates temperature, humidity, air pressure, wind speed, wind direction, rainfall, ultraviolet light, particulate matter, cloud images, and an optional real-time video terminal system, which can meet the needs of meteorological observation in various industries, and can be integrated into the observation network of the national meteorological departments. The communication protocol can be opened and connected to the terminal software to facilitate the user to collect and process data according to end customers' requirements.
