Argh -- $$$$ There used to be "spider" sensors that were cheap but I heard they shut down. What you need is something based on those "stamp" CPU's but I donno who is making such...
I suppose if one had enough time and interest, and some Java skills, you could make something out of these:
http://www.ibutton.com/ibuttons/thermochron.html http://www.ibutton.com/TINI/applications/sertoeth/ Oops, somebody's already done it: http://www.maxim-ic.com/appnotes.cfm/appnote_number/1048/ln/enLooks like the total hardware cost would be around $100 for the TINI and board, and $8 for each sensor (iButton and holder). I have little time and no Java skills, otherwise it looks like a cool project. If somebody wants to develop a machine room temperature monitoring network out of them, I'd be a beta tester ;)
