Davis Wireless Weather Envoy 
Wireless Weather Envoy
Receive data from a wireless Vantage Pro2 integrated sensor suite or wireless Temperature, Temperature/Humidity, or Leaf Wetness & Soil Moisture/Temperature stations, and post it to your computer without a console! When used along with a WeatherLink data logger and software package, Weather Envoy will collect and store data from the outdoor sensors. Both the wireless and cabled versions include an AC-power adapter. Either may also be run using one of our solar power kits.
Compatible with Vantage Pro2 only; not compatible with original Vantage Pro.
