Overview

Davis Instruments Weather Envoys

Davis Instruments Weather Envoys provide a way to transport weather data from your Vantage Pro2 or Vantage Vue weather station into your Windows XP, Windows Vista, Windows 7, or Macintosh (OS X) computer using Davis WeatherLink software.

Weather Envoys include the data collection and logging functions of the Vantage consoles, but in a smaller package that can be placed next to your computer or in a field installation. They may be used to free your wireless console from the need to be near the computer, or they can be used in place of either a wired or cabled console. Cabled and wireless versions of Weather Envoy stations are available!

When used with Davis WeatherLink software and data logger, they allow you to view, store, plot, analyze, export, share, and print your weather data from your PC or Mac. This is a must for the serious weather researcher and avid amateur weather watchers!

Track and analyze your weather data effortlessly with one of these Davis Instruments weather envoys from DX Engineering!
