Changing the source code of a module isn't going to affect that module
in a running program if it's already been imported. You can use the
importlib.reload function to force a module to be reloaded, but this
is generally anti-recommended. If not done correctly it can result in
multiple versions of the module being simultaneously in use, leading
to confusing error conditions.

It sounds like you're not trying to update the code anyway, just the
data used in the code. For that, you'd be better off putting the data
in a data file that your "sensors.py" would read from and re-read on
every iteration.
