One thing you get with cheap is a +/- 10V full scale range. A thermistor and resistor into the DATAQ might work better. Maxim/Dallas One-Wire devices are another possibility There's tons of PIC code out there to interface to them. The sensors are cheap (few bucks, depending on whether you buy raw device, or you get one potted with a cable) Sparkfun.com has them, among other places. There's also a whole raft of USB temperature loggers out there from Onset (HOBO) or DataQ or a variety of other companies. They tend to run in the $80 range (if someone knows about a battery powered temperature logger in the under $25 range, I'd love to hear about it) And, of course, a DMM with a RS-232 interface is another possibility _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
