HMT is about saving money, but when something is that cheap i dont see it as worth the effort

I know how to do a 0 to 5 V power supply but is that what you needed?

Rene, it has an amplifier in it that is scaled to provide a 0-5 volt output.

Thermocouples produce small amounts of voltage depending based on the temperature difference of the two junctions. Forewarned, it is not completely accurate.


If you want, I'll build you one when I have some spare time.

$40 is a lot more than $10 in parts.
