Lark Weather Station Sensor

SKU: EDU0157-EN

The Earth's atmosphere, influenced by wind speed/direction, temperature, humidity, and air pressure, requires precise detection for understanding its movement. Traditional meteorological data acquisition is cumbersome (integrating multiple sensors, wiring, programming, debugging, assembly), challenging educators and students. Commercial weather stations are specialized, non-redevelopable, and lack adaptability. To address these issues, we present the Lark Weather Station.
