The CRAFTSMAN Personal Weather Station provides the indoor and outdoor temperature and humidity, wind speed, and barometric pressure thanks to a built-in barometer. By having the knowledge that an indoor/outdoor thermometer and anemometers provide, your garage, workshop, or toolshed will receive an immediate upgrade with this indoor weather station addition. The best weather station for quick and easy temperature, humidity, and wind speed viewing, this weather gauge also uses your hyperlocal weather data to provide you with a personalized forecast 12 hours from your current conditions. With the data coming from your own yard, you’ll have the most accurate forecast available for your exact location and will be able to plan your outdoor projects accordingly. The display also provides the date and time (automatically adjusting for daylight saving time) to make for the perfect workshop weather clock. To provide you with even more weather knowledge, you can use the arrows on the display to view high and low records for temperature and humidity. You can also view current, average, or peak wind speeds, which help you understand if you can get to your outdoor build or paint job — or even simply take the dog for a nice walk! You can manually calibrate temperature, humidity, and barometric pressure for precise measurements — only a feature that the best home weather stations can boast. The outdoor weather station sensor requires four (4) AA alkaline or lithium batteries (not included). The indoor weather station display is powered by a 5V adapter and takes three (3) alkaline or lithium batteries for optional yet recommended battery backup. This weather station comes with a one-year limited warranty.
