Plan the day with confidence with your own weather station and weather prediction information with pinpoint accuracy right from your own backyard. The AcuRite 01121M Wireless Color Weather Station uses patented Self-Calibrating Technology to provide your personal forecast of 12 to 24 hour weather conditions. Self-Calibrating Forecasting is generated from weather data measured by a sensor in your yard - giving you the most accurate forecast available for your exact location.

You may custom program temperature and humidity alerts to notify you when a value has been reached or exceeded. Display stands upright for a tabletop/desk or may be mounted on a wall. The wireless outdoor sensor features a thermometer and hygrometer. One-year limited warranty. It's more than accurate, it's AcuRite.
