WeatherLink for Vantage Pro2 Sprinkler & Irrigation Control Module.
Use your Vantage Pro2 to turn your irrigation system on or off based on current weather conditions no more watering the lawn when it's raining!

Installation is quick and easy. Connects to most common irrigation systems including Rain Bird, Rain Master, and Toro. For the industrial controllers used in agricultural and turf management, provides electronic pulses for wind, rain, and evapotranspiration.

For homeowners, use the alarm settings in the Vantage Pro2 console. Set the alarms to water your garden before a hard freeze hits, or to turn the system off if it starts raining. Add our optional solar radiation sensor, and you can even set the alarms to turn the system on or off based on evapotranspiration. Datalogger also simultaneously logs and stores the data, which can later be downloaded to your PC for all the graphing, charting, and analysis inlcuded with our standard WeatherLink. 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 for each computer.

Includes streaming data logger, software on CD, and an 8ft (2.4m) cable to connect the data logger to your computer or modem. For downloading to a PC, you need Windows 95/NT4.0/98/2000/ME/XP and one free serial port. Compatible with both original Vantage Pro and Vantage Pro2. Not for use with WeatherLink for Mac... sorry. FREE Shipping USA & Int'l via USPS or UPS - usually 3-7 days in USA; 4-10 days Int'l
