This is the U2000 base station. (Note: I have upgraded to the 2100 which is similar in appearance.) The wire exiting from the right of the unit is the serial data out to the computers.
Humidity gauge is working normally.
Outside thermometer is in sunshine for a few hours during spring and summer. I am using a shielded sensor which allows accurate readings in direct sunshine.
Barometer reading appears to be accurate.
Wind speed and wind direction are working normally. The wind sensor was upgraded to the "Pro" version this spring which is larger and detects very low wind flow. Of course, that is not a big issue in Rochester where the wind is seldom calm!
Rainfall measurements appear to be accurate.
The Ultimeter 2100 provides a continuous serial data stream which currently feeds two computers.
A Windows XP computer is used to run amatuer radio APRS software sending the weather data out on 144.39 MHz FM packet (amateur radio callsign AA0SM). That system is currently off the air due to a hard disk failure.
A Linux computer is running a weather server program which serves weather information using tcp/ip sockets. Also running under Linux is MisterHouse, a home automation program written by Bruce Winter who previously resided in NW Rochester. MisterHouse connects to the weather server and collects the weather data which it then uploads periodically to The Weather Underground. Another client program collects data from the server and posts it to a web page every five minutes.
Here are some images of the weather station components.

This shows the anemometer and wind direction indicator (hidden as it's
aimed at the camera). Amateur radio antennas are also visible in the
photo.
The temperature/humidity sensor is located on northeast side of the
house. It is in shade most of the time, but in sunshine during some
morning hours part of the year (spring, summer). The solar shield
allows direct sun exposure.
This is the electronic rain gauge. It meters the flow of water into a
known drop size and counts the drops as they flow through the gauge.
