Abstract
The occupancy status of a building space may be determined by sensing an indication of motion in the building space, in response to sensing the indication of motion in the building space, starting an occupied time period having a length during which the building space is indicated as being occupied, determining a measure related to a number of subsequent sensed indications of motion in the building space during the occupied time period, and selectively adjusting the length of the occupied time period based on the measure related to the number of subsequent sensed indications of motion in the building space during the occupied time period.
