Office Monitoring -- Wim Heirman
This site shows live temperatures from my office (Office), my PC's air exhaust (Atuin) and outside (Outside). The first ones are measured with two DS1820's and a DS9490B adapter. The outside temperature is taken from wunderground.com.
You can clearly see the correlation between inside and outside temparture, and when my PC is hard at work (not necessarily correlated with when I am hard at work ).
The site is made using OWFS (owserver+owpython), RRDtool for data storage and creating graphs, and some Python code to stitch it all together.
