i've been looking at the iButton stuff.
you can get an evaluation kit from them (1 temp sensor and RS232 hookup)
for $25.

the advantage of using the iButton (actually 1-wire network) stuff, is that
you can actually run multiple sensors off the same wire.
they have temp and humidity sensors.
more info on 1-wire from:
http://www.dalsemi.com/
http://www.pointsix.com/
using a *nix box and ucd-snmp, it wouldn't take much to make the data snmp
addressable.
i'm planning on putting some of these in my cottage to look for leaks and to
gauge the enjoyment factor of the upcoming weekend.
although, i'm still trying to figure out a way to detect the frequency and
strength of the bugzapper hits, so i can MRTG the blackflys.
