What I'm using is dallas 1wire stuff to do such things.
The dongle (which is available as USB too) connects
to the host and you have a lib with bindings even to python
for it: http://www.owfs.org/

The other end is just a bus with a telephone wire...

The most interesting part might be temperature sensors but
there are a lot of GPIO chips, electronic resistors, A/D converters
etc. available. Most of the stuff can be even ordered as sample
from dallas/maxim.

Tino
