> Are there any recommendations for other off-the-shelf sensors= > worth looking at? Consider the TEMPer USB units from eBay. Their main advantage is low cost. They have a temperature sensor in a thumb drive size USB module. At least one model comes with a slightly bulky sensor on the end of a 3ft cable. Most of the low cost units have a fairly coarse step size. Please let me/us know if you find (or build) a good high resolution setup. I assume that will be a thermistor and good DAC. -- These are my opinions. I hate spam.
