Thermopile Calibration

Hello,

I would like to know a protocol to calibrate a thermopile and its
amplification.


By calibration I mean exciting the thermopile (by changing the
temperature of the object as well as the ambiant temperature) to
determine the coefficients that link the thermopile and the
thermopile's thermistor outputs.


I am a hobbyist and I do not have too much equipment at home... Non
need to say the protocol should be lightweight!


Thanks!

Well, get a couple of thermometers, a voltmeter, an ammeter, an
assortment of loads, a heat source of some kind, and a lab notebook
and pencil, and measure the output at various temperature differentials,
loads, and so on.

Good Luck!

The thermopile measures whatever it measures, be
that ambient, or radiation, reflections.

You can sort of calibrate it by having it at a
constant temperature and point it to a scenery
with constant temperature. Eg open the fridge
and take a reading. Or open the cooking stove
and take a reading.
