New Weather Station

I've been interested in having a weather station that connects to a computer for quite a while. A couple of weeks ago woot.com had one that fit the bill and was reasonable priced. The first picture show the view on the computer screen that displays: wind direction, speed and gusts, rainfall, indoor and outdoor temperature including max and min and barometric pressure. The second picture show the wind and rain equipment I installed at the roof peak. The system seems to work quite well but I'm afraid the outside temp is registering about 5 degrees high. I'll try to figure out how to calibrate it.
