Space (Sky) is a lot colder than ground at the IR frequencies used by the thermopiles. I believe when there is something between sky/space like clouds that issues arise. -David1

Hi,

since the IR sensors control is based on the fact the the sky is colder than the ground, Is there any problem using it over snow or ice in a warm day?
