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 ;) Regards, Michel
