With its large & vibrant color display, you get a clear view of your weather data, even from a distance. The weather station automatically calculates local temperature and humidity data. When plugged into the power adapter, you can set the backlight to stay on continuously and adjust the five levels of dimmer brightness. Includes one outdoor sensor that monitors the temperature, humidity, and past 24-hour weather data for one location — from up to 100 meters. The weather forecast feature displays five kinds of weather: Sunny, Sunny to Cloudy, Cloudy, Rainy, and Snowy. These are based on the hourly calculations of indoor/outdoor temperature, humidity, and built-in barometer. What's more, the built-in RCC atomic clock with DST accurately adjusts your time & calendar with the WWVB radio signal daily.
