The AcuRite Atlas Home Weather Station High-Definition Display with Built-In Barometer, when used with an AcuRite Atlas outdoor weather sensor (SOLD SEPARATELY), provides indoor/outdoor temperature and humidity, wind speed and direction, and rainfall measurements. Protect your family, house, and garden with minute-by-minute updates in weather changes, including wind speed and direction (thanks to the anemometers and wind vane on the AcuRite Atlas), and UV index. Much more than a typical weather clock, this display provides indoor temperature, humidity, barometric pressure, heat index, dew point, and wind chill. Create your own weather center with a hyperlocal weather forecast 12 hours from your current conditions — more high-tech than a storm glass and a feature only the best weather station can boast! This personal weather station gives you the ability to create customized, programmable alarms when critical conditions change so you can identify emerging weather events and take necessary action. A perfect gift for Christmas, Father’s Day, and Birthdays, this weather tech gadget is perfect for smart-home optimization. This indoor outdoor weather station is AC powered and takes three (3) AAA batteries for backup purposes only (batteries not included). This weather station comes with a one-year limited warranty.
