Have you got workstations in those rooms? If so, relatively cheap and easy: http://www.amazon.com/Powered-Thermometer-Temperature-Sensor-Data/dp/B0054U4YKI/ref=sr_1_12?s=electronics&ie=UTF8&qid=1381934472&sr=1-12&keywords=usb+temperature Less than $15, there may be enough cable to position the sensor somewhere useful. If you're handy or want to hire someone (Amazon Mechanical Turk? Craigslist?) to build it for you, Analog Devices published a circuit design that looks inexpensive http://www.analog.com/en/circuits-from-the-lab/cn0153/vc.html -- Charles _______________________________________________ Discuss mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
