| Nov 14, 2014 at 15:14 | comment | added | pentane | Hi @Cerin, as I said in my answer, the comments are misleading and heat is not a factor. The IR proximity sensor you are using does not work by detecting hot objects. It comes with an IR flashlight (LED) that is very bright compared to the IR heat of the object, so even an extremely cold object which doesn't produce much of its own IR will be detected as long as it reflects the IR of the LED. | |
