VANTAGE VUE
®
The Vantage Vue® (#6250) wireless weather station includes two components: the Integrated Sensor Suite (ISS) (#6357) which houses and manages the external sensor array, and the console (#6351) which provides the user interface, data display, and calculations. The Vantage Vue ISS and console communicate via an FCC‐certified, license‐free frequency‐
hopping transmitter and receiver. Frequency‐hopping spread‐spectrum (FHSS) technology provides greater communication strength over longer distances and areas of weaker reception. User‐selectable transmitter ID codes allow up to eight stations to coexist in the same geographic area. (The Vantage Vue console can also receive and display data from any Vantage Pro2™ or Vantage Pro2 Plus ISS. The Vantage Pro2 Plus includes two additional sensors: the UV sensor and the solar radiation sensor.) The console may be powered by batteries or by the included AC‐power adapter. The wireless ISS is solar‐powered with a battery backup. Use WeatherLink™ for Vantage Vue to let your weather station interface with a computer, to log weather data, and upload weather information to the internet.
The Vantage Vue station relies on passive shielding to reduce solar‐radiation induced temperature errors in the outside temperature sensor readings.
