Davis Vantage Pro2 GroWeather Sensor Suite - Wireless with 24-Hour Fan

Accurate, reliable weather monitoring

The versatile Davis Vantage Pro2 GroWeather Sensor Suite combines an anemometer, rain collector, temperature, humidity and solar irradiance sensors into one package for rugged reliability and performance. It collects outside weather data and sends the data to a receiver such as a Vantage Pro2 console. The wireless sensor suite can also transmit data to wireless Vantage Connect, Vantage Vue console, Envoy8X, or wireless Weather Envoy. The wireless sensor suite is solar-powered and sends data via radio.

The sensor suite includes a rain collector, temperature sensor, humidity sensor, anemometer, and solar radiation sensor. Temperature and humidity sensors are mounted in a passive radiation shield to minimise the impact of solar radiation on sensor readings. The anemometer measures wind speed and direction and can be installed adjacent to the sensor suite or apart from it. The transmitter shelter contains the "brain" of the sensor suite: the sensor interface and the transmitter. It collects outside weather data from the sensor suite sensors and then transmits the data to your Vantage Pro2 console, Vantage Vue console, Weather Envoy, Envoy8X or Vantage Connect.
