Help selecting Temperature sensor


Joined Jan 16, 2013
Ad585 is a thermocouple amplifier with internal cold junction compensation, you wouldn't need another sensor. You can power it with a 9v battery. I was able to make a great circuit with a sharpie and some etching. It's extremely simple

Otherwise you'll need a thermistor (glass bead 100k from Epcos has a pretty quick response) with some kind of interpretation circuitry.

You could build a fairly nice analog circuit with a thermistor that could control pretty much anything relative to the temperature with an opamp or something. Depends on what you intend to do with the temp info.

Or you could just buy an infrared temp gun ;)
