Trying to use one of these to measure temperature, but having no luck. It doesn't behave like a K type, or a J type thermocouple. Wonder if it's actually an LM35 or somesuch. It has a "stereo" type 3mm phone plug, so I wonder if it's actually +, - and output.
Anybody find any technical information about these? All's I can google is places to buy them and instructions for grilling.
