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 currently not working. I have reverted to the simple external thermometer without the humidity sensor. I will probably not attempt to fix it until Spring.
Outside thermometer is in sunshine for a few hours during spring and summer. I am now using a shielded sensor which allows accurate readings in direct sunshine. (I have temporarily reverted to the plain temperature sensor which reads fairly accurately until we have vastly increased sunshine and early morning warmth in mid-spring.)
Barometer reading appears to be accurate.
Wind speed and wind direction appear to have a problem. The anemometer is freely moving, but I have not yet attempted to debug the wiring.
Rainfall measurements appear to be accurate.
The Ultimeter 2100 provides a continuous serial data stream which currently feeds two computers.
A Windows 98 computer is running amatuer radio APRS software sending the weather data out on 144.39 MHz FM packet (amateur radio callsign AA0SM).
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 also happens to reside 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.
