Abstract
A heat sensor has the ability to correct for errors introduced during temperature changes of the hot junction of the thermopile for the heat sensor. For example, the effect of temperature changes at the hot junction of the heat sensor relative to the cold junction is mathematically modeled such that the effect on the temperature determination can be corrected given certain information relating to the thermopile, its electrical output, and the temperature history and current temperature of the cold junction. By accounting for these factors, a processing device can modify the temperature determination output for the heat sensor while correcting for error introduced by temperature changes at the hot junction as determined by the mathematical model.
