I use 1-wire devices with CentOS.
See http://owfs.org/ 
If you google a bit there are many suppliers who sell complete kits for
serial and USB (I use USB) connections for a fair price.
Maybe it's a bit overkill for 1 sensor, but its easy to connect many
sensors to a machine (I have about 20 :) ).

You can make it really cheap if you have some soldering skills ;)
