I have used a USB-DUX to create a temperature feedback controller, using
the comedi python module. It can be used to log temperatures, I have
done it. I did not need great precision or accuracy. I just used the
temperature sensor (LM35) recommended on the web site
http://www.linux-usb-daq.co.uk/howto2/temperature/. This was good enough
for me.

Speak with Bernd if you need to know more. Everyone at Incite were very
helpful.
