The TFA Spun is a digital weather station. The large digital numbers on the large color display provide the time, day, date, air pressure, temperature, and (indoor and outdoor) humidity level. Thanks to the clear images, you'll see what the weather's like today with 1 glance. The weather station also gives the weather forecast for the next day. This way, you'll immediately know what to expect tomorrow. The display runs on both AC power and batteries. You can install the weather station in any location you desire, without having to use any cables.
