2p.25p.The multifunctional weather station is equipped with manyfunctions providing thorough weather information to you.The receiver unit has a clear, easy-to-read display thatshows weather forecast, indoor temperature, pressure,moon phase, time and date, as well as the temperaturemeasured and transmitted by the sensor. It is able to re-ceive and display readings from up to 3 remote sensors.The receiver unit retains the minimum and maximumtemperatures and relative humidity readings measured atvarious locations. The 433 MHz technology means no wireinstallation is required and you can place the sensorsanywhere you like.With radio controlled function, the current time and dateare automatically synchronized with the time signaltransmitted from Frankfurt Germany (DCF77) / UK (MSF) /US (WWVB). The signal can cover a distance of about 1500km from the related transmitter.
