Add in a swissflow flowmeter and measure flow rate as well and you should be able to set it up a fairly simple to use digital testing bench for under $200. Use a spare PC (everyone has those right?) for monitoring the temperatures and logging and K7Burn for loading CPU on test box.

found info on connecting to serial port

cheapest source for DS1820 is $5 each, from http://www.futurlec.com/Dallas/DS1820pr.shtml ????

am I missing something easy?

apparently MMZ_Timelord's project is not getting off the grounmd, would like to investigate other options
