Always stay on top of the weather with your own CRAFTSMAN Personal Weather Station. Combining such tools as a wireless indoor/outdoor thermometer, an indoor/outdoor hygrometer, a wireless rain gauge, wind vanes, wind anemometers, and a barometer, this home weather station measures indoor and outdoor temperature and humidity, wind speed, wind direction, rainfall, and barometric pressure. Plus, it provides a personalized forecast 12 hours in advance from your current conditions, so you’ll always know when inclement weather is ahead and when to move your outdoor plans inside. In addition to the outdoor measurements, the HD display exhibits the time, month, and date, making for the perfect weather clock for your workshop, tool shed, or garage! The included outdoor, weather-resistant lightning sensor tracks lightning strikes up to 25 miles (40 km) away and provides a visual and audible warning, a feature only the best weather stations can boast. Both the 5-in-1 remote weather station sensor and lightning sensor require four (4) AA alkaline or lithium batteries each (not included). This weather station comes with a one-year limited warranty.
