          Calling :meth:`set_sampling_strategy` requires the requested strategy to
          be memorised so that it can automatically be reapplied.  This method
          causes the strategy to be forgotten.  There is no change to the current
          strategy.  No error is raised if there is no strategy to drop.
  
          Parameters
          ----------
  
          sensor_name : str
              Name of the sensor
