This webpage is based on the Menet pressure server but was ported to Windows.
Perl, ActivePerl, is used to collect and process the data.
Some of the data is gathered using the Geo::WeatherNWS and Geo::WeatherNOAA Perl modules.
Update: Having some current issues with the Excel/OLE capabilities so the plots are now generated using GD:GRAPH.
The graphs are generated by Excel using Perl's Win32:OLE capabilties.
The data is collected and the plots are updated every 30 minutes.
The temperature data above is from a serial interface temperature sensor kit from QKits which uses a Dallas Semiconductor DS18S20 sensor.
Thermd is the same link as on the Qkits page. His perl code was a very useful reference, although it was a Unix variety and much more complicated than I wanted at the moment.
And here is another link, Hilversum Temperature, to a good snippet of reference Perl code.
And you can find some of my code here.  Use for reference only.
Here is information on accessing Menet's pressure from the command line, telnet, and C programs.
