The TFA Spectro easily shows you all the measured data. The digital weather station displays time, temperature (indoor and outdoor), and the weather forecast. It measures the air pressure to give you a weather forecast for the following day. The weather station also has an outdoor sensor. This measures the outdoor temperature and sends this information via frequency to the indoor weather station. Mount the weather station to the wall or place it on your nightstand. The station runs on batteries, so you don't need cables or a socket.
