This AcuRite Compact Digital Wind Speed Forecaster 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.

The weather station's illuminated color display features indoor/outdoor temperature and humidity, wind speed, wind chill, dew point, heat index, barometric pressure, moon phase, Intelli-Time clock, and calendar. Wind information includes current wind speed, average wind speed and peak wind speed readings that are tracked and updated every 18 seconds.

Intelli-Time clock automatically adjusts for Daylight Saving Time (DST). Humidity level indicator easily conveys a low, high or ideal indoor humidity level. Display stands upright for tabletop use.

The patent-pending 3-in-1 wireless weather sensor features 3 different technologies in one easy-to-mount unit: thermometer, hygrometer, wind speed anemometer. It is easy to set up and includes mounting hardware.

Display operates on the included 5V power adapter or three AAA batteries and the remote sensor requires four AA batteries (no batteries included).
