The thermopile sensor delivers an output signal proportional to the heat flux. The heat balance equation is the basis of any quantitative temperature measurement ( S > voltage sensitivity). U TP = S * P rad = S * K * (obj *T obj 4 – abs * T amb 4) It describes that the output voltage is a function of the object and the ambient temperature. For a fixed ambient, the theoretical output voltage ...
