It depends on what you want to achieve. If the FSM models some kind of
session and there can be multiple sessions attached to a single sensor,
then, obviously, the FSM should not be a singleton. If the FSM models
the sensor itself, then it should be a singleton as well. However, in
the latter case I would made the sensor a member of the FSM.
