WS7 Weather Sensor

An all-in-one solution weather sensor from LAMBRECHT meteo, an AEM brand, Germany. A compact and system-capable sensor with wind direction and speed measured by ultrasound sensors. Air temperature, humidity and pressure values are also determined and the dew point can be included. The equipment is protected from the deteriorating effects of the climate to ensure improved and accurate measurements.
