Yep, that has indeed between the primary and only use-case for QtSensors so

Adding new sensors is quite possible, adding a QHeatSensor with an associated 
sensor backend would certainly be technically feasible.
This could even be done outside of the official QtSensors, as all the API for 
that is public (well, except adding new QML types, but then, you can export 
the QSensor subclass instance directly to QML as well).

Right, I am not sure if these kind of sensors would fit very well. Technically 
it would certainly be possible. Maybe Lorn Potter, the maintainer, can answer 
about the vision of QtSensors and what type of sensors it should encompass.
