Say goodbye to your old-school storm glass, wind vanes, and anemometers, and say hello to the AcuRite Iris (5-in-1) Wireless Home Weather Station! Way more advanced than a basic indoor/outdoor thermometer, the indoor weather gauge display provides you with the indoor and outdoor temperature and humidity, wind speed, wind direction, and rainfall. It also acts as the perfect weather clock, as it provides the time, date, and moon phase, in addition to a hyperlocal forecast 12 hours from your current conditions calculated by data collected by the wireless outdoor sensor in your yard. The outdoor weather station with rain gauge measures conditions and relays the data to the display, so you’ll know what it is like out in your backyard without even having to go outside! Plus, you’ll have remote monitoring capabilities that will let you check your digital weather station’s hyperlocal data on your phone using the AcuRite NOW® mobile app. With all of your hyperlocal weather data at your fingertips, you’ll be able to boast to your neighbors that you have the best weather station! The remote weather station uses solar power to regulate internal temperature for more accurate temperature measurements, which can be sent — along with the other weather data — from up to 330 feet (100 meters) away (and through walls) using a 433 MHz wireless signal. The best-in-class weather display will look great in your personal weather center or rec room next to your sports ticker with its straightforward readability from almost any angle. With this professional home weather station, Wi-Fi connectivity allows you to set custom alerts that can be received and viewed on your AcuRite NOW app. These alerts make this the perfect weather station to keep tabs on your summer home or use as an RV weather station at the campsite. This weather underground weather station also allows you to share your weather data online with the weather underground community. The indoor weather station is AC-powered and also takes three (3) AAA batteries (not included) for optional backup in case of a power outage. The wireless outdoor sensor requires four (4) AA batteries (not included, lithium recommended for optimal performance). A perfect gift idea for Christmas, Father's Day, or birthdays, this weather station comes with a one-year limited warranty.
