When the ambiant temperature where device is running is 25C... and the
emisivity of the target is selected appropiately. With a wrong
emisivity, the error may be up to 20% or more.
I have really doubts that module it can measure in -25C...+30C with
+/-2% acuracy, but that is my problem...

For a real temperature measurement a ratiometric infrared tehnique
could be the true solution.
