What's the difference between the usual DIY IR guns and the ones which
they are using (Asia) to check body temperature in the epidemic?

The main difference is that the ones intended for use on humans or
animals are calibrated for the emissivity of human skin which isn't all
that close to being a black body for thermal radiation.

Do they have settings for different skin colours? Like before and after a
holiday in the sun? ;-)
