Behind the door.

Indicate, in an indirect way the outside temperature. This handle allows dual temperature reading and allows comparisons between external and internal temperatures. It uses the fact that the handle is an object connecting both the inside and the outside with the aluminum axis which is at its core. The indoor handle will have a second skin separated by an insulating material, which will evolve according to changes in the outdoor temperatures.
