I have used the IR sensors just for spot checking hard to reach areas for approximate temps to see if they are close to set points. like when a Maintenance man does "the run" for his shift at a Hotel etc. or extreme temp locations or hazardous surroundings preventing access.

"true" means from a supply house for Electricians and is like $8 a roll instead of $1

It has something to do with the beam refraction.
