The AcuRite Atlas Weather Station with a Gray HD Display for Temperature, Humidity, Wind Speed/Direction and Built-In Barometer (01125M) also provides indoor temperature and humidity, rainfall measurements, and UV index readings. Protect your family, house, and garden with minute-by-minute updates in weather changes, including the outdoor temperature, humidity, wind speed and direction (thanks to the anemometers and wind vane), rainfall, and UV index. Much more than a typical weather clock, you’ll get indoor temperature, humidity, barometric pressure, heat index, dew point, and wind chill information. 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! When equipped with a lightning sensor (sold separately), the AcuRite Atlas measures lightning strikes detected up to 25 miles away. A perfect gift for Christmas, Father’s Day, and Birthdays, this weather tech gadget is perfect for smart-home optimization. The outdoor sensor takes four (4) AA batteries (not included), and the HD display is AC powered and uses three (3) AAA batteries for backup purposes only (batteries not included). This weather station comes with a one-year limited warranty.
