Add weather and indoor environment knowledge to your home! This Square Color Weather Station uses patented self-calibrating technology to provide a hyperlocal forecast 12 hours from your current conditions — pinpointed to your exact location. The backlit LCD screen provides easy-to-read information in a quad-divided format. The wireless outdoor sensor relays outdoor temperature measurements to the indoor weather station display, which also provides the indoor temperature and humidity (with trend arrows), barometric pressure, and the date and time. The display also exhibits today’s high and low records for outdoor temperature and an indoor humidity level comfort icon. Set up alarms for when a customized temperature or humidity measurement has been reached or exceeded. The display operates with the included AC adapter and takes three AAA batteries (not included) for optional battery backup. The outdoor sensor requires two AA batteries (not included) and features powerful wireless technology, a weather-resistant design, and an integrated hanger for easy mounting. Indoor temperature range: 32-122 degrees F. Weather station dimensions: 5.06” H x 5.36” W x 1.19” D. Outdoor temperature range: -40-158 degrees F.
