WeatherLink for Vantage Pro/Pro2
For the ultimate in weather monitoring, add WeatherLink to your Vantage Pro or Pro2. The data logger fits neatly into the console or Weather Envoy, storing weather data even when its not connected to your PC. Later, download the data and use the software to create graphs, generate summaries, and more. Expanded Reporting. See current conditions at a glance on the instant weather bulletin. Graph data on a daily, weekly, or yearly basis. Or view multiple weather variables at the same time to see their relationships.

Create Weather Watcher Reports in NOAA National Climatic Data Center Format. View special reports on heating degree days, cooling degree days, and fuel-oil demand. With optional sensors, see reports on evapotranspiration, leaf wetness, soil moisture, soil temperature, sunburn risk for each skin type, and solar energy.

Sharing Your Weather Data. Help the National Weather Service develop improved weather prediction models by submitting your data to the Citizen Weather Observer Program via APRS or the Internet. Create your own weather website or post weather conditions to a LAN using our included HTML templates. Upload other files (such as images from a webcam) along with your weather data. Participate in The GLOBE Program, an international weather-related science program for students from elementary through high school, supported by NASA and NSF.

System Requirements: Requires Windows 95/NT4.0/98SE/2000/ME/XP with serial port. Weather website features require Internet Explorer 4 or above. Also available in a USB version and a version for Mac OSX. Includes software on CD, data logger, and 8ft (2.4 M) cable to connect the data logger to your computer. Choose a logging interval of 1, 5, 10, 15, 30, 60, or 120 minutes. Depending on the logging interval, store up to six months of data before downloading. To track multiple stations on the same computer, add one WeatherLink for each station.

To view the same on multiple computers, add one Extra User License Kit for each computer. Compatible with both original Vantage Pro and Vantage Pro2. FREE Shipping USA & Int'l via USPS or UPS - usually 3-7 days in USA; 4-10 days Int'l

Data Logger Archived Data
The Data Logger stores up to 2560 archive records (one 52-byte record per archive interval) for later transfer to your computer. The archive records are stored in 128K of non-volatile memory; protecting the data even if the console loses power. Maxima, minima, averages, and totals are taken over the archive interval.
