The Youshiko wifi weather station has 6 sensors in a single unit for you to position outside, preferably away from buildings if the wind data is to be accurate. The transmission range is 150m and and can pass through one or two walls to reach the receiving console. The receiving console just has a single power cable and has no connection to your PC. There is also a single separate indoor sensor for temperature and humidity supplied - though you may connect wirelessly up to 7 of these indoor sensors.

The display itself can be set to loop between 256 colours or you may choose one of 8 colours manually, another option is to have the display colour automatically change with the outdoor temperature. Apart from your weather data you'll see the time, calendar and day of the week.

This Youshiko weather station with Wifi connectivity and direct upload to Wunderground website is one of the most advanced personal weather stations available at this mid-range price point. Not only can it support the one extra temperature / humidity sensor for the indoors - but you could monitor up to 7 rooms by buying extra sensors. This kind of flexibility isn't found on the cheaper USB model. Also the USB model must be connected to switched on PC for the Wunderground updates to work, if you're keen on that feature this unit is a far better buy.
