The state-of-the-art La Crosse Technology WS-2812U-IT Professional Wireless Weather Center features La Crosse' s new state-of-the-art wireless " Instant Transmission" technology, featuring temperature and humidity data updates every 13 seconds, wind data every 17 seconds, and rain data every 19 seconds.

The La Crosse WS-2812U-IT can monitor a number of weather variables including indoor/ outdoor temperature and humidity, rainfall, wind speed and direction, and barometric pressure. The weather center also includes time and date display, weather forecast icons, and user-selectable alarm settings for a number of different weather conditions.

La Crosse' s Heavy Weather Pro software allows you to use a PC to monitor and record weather data received from the WS-2812U-IT via a proprietary USB device that' s included with the weather station. You can monitor and record a variety of data collected by the various weather station sensors. You can also review weather history data, and analyze trends and tendencies over time using the software' s charts and graphing features.

The WS-2812U-IT comes complete with wireless indoor console, temperature and humidity sensor, rain gauge, and solar-powered anemometer.

Note: We do carry a magnetic compass to help you orient your anemometer to true north. For more information on set up, please visit the anemometer page on our WeatherShack education center.
