We have bought, but haven't yet setup (It would be a good student project! )
one of these "Goose" boxes:
http://www.itwatchdogs.com/wxgoos-instructions.shtml
which has line drivers to allow one to setup a network of the
one-wire sensors...the individual sensors are pretty cheap
(but it took about 3 months to order a box of 100 from the US)
cheers,
Alex
