This is an excellent tool for anyone who is weather obsessed to any degree. The Hama EWS-1500 is a full weather station (weather measuring and recording device). The Hama EWS-1500 Weather Station measures humidity, atmospheric pressure, temperature, rainfall and wind speed. It does all these things using wireless outdoor sensors which communicate the information back to the unit's base station. The range of the wireless signal is up to 100m in clear line of sight. The idea is that you mount the sensors in the garden and wirelessly monitor the results from the comfort of home. The base station includes a clock/calendar function using the DCF radio clock (automatic adjustment of the time to the world´s most accurate clock). An alarm, a perpetual calendar (up to 2099) and several other functions. More information on the Hama EWS-1500 Weather Station.
