Yes, no functional difference but the detection

Yes, that's also my concern on the code of detection. I don't have any other sensors as
LM75C to try, so thinking maybe some other guys can help extend it if needed in future.

Understood, we can have the instantiating script but just don't want limit the detection.
Thanks!
