This Honeywell weather forecaster monitors temperature and humidity using a wireless sensor with a transmission range of 100ft. The included atomic clock receives its signal from the U.S. Atomic Clock in Fort Collins, Colorado and will automatically adjust for daylight savings time. This unit also displays phases of the Moon, a 24-hour barometric pressure history chart, and features a programmable ice warning alarm.
Requires 4 AA batteries (two for the remote sensor and two for the main unit).
