Thanks:

Data was sampled by a La Crosse WS2315, over a serial interface, to a Debian Linux server, into an MySQL database, using Kenneth Lavrsens Open2300 software.

This page was served by Python Server Pages (Spyce), through an Apache web server, using mod_python. The plotting is done with MatplotLib and some data processing is done with NumPy.

Thanks to all this free and open software, my only effort and contribution was to set up the weather station, system software, and program a simple Spyce page, which you can get here: ws2300.spy.txt. Not elegant, and far from well commented, but hey ... it actually works for me :-)
