I am reading an app note written by Cypress which is attached. Actually we are interfacing thermopile attached its datasheet also.

We are able to measure the Vtp of thermopile and convert Rth to NTC_temperature.

Now we have trouble converting these two readings to Object temperature.

Can anyyou tell in a bit more detail how to do it further?

Our area of it interest of object temperature is 35 to 42C and Ambient goes from 0 to 50C.

ViTa,

I believe that Excel has minimization function, which can optimize K and n over the dataset.  Something like equation solver. I am not an expert on that.
