Abstract
An occupancy detection network controls illumination from lighting devices in each of a plurality of defined areas. Motion detection modules and sound detection modules provide output signals based on detected occupancy in each defined area. The sound detection modules automatically adjust sorting criteria over time in accordance with identified sound characteristics associated with occupancy, detect sound in the associated defined area in accordance with the sorting criteria, and provide an output signal based on the detected sound. A central lighting controller is linked to the detection modules via a common bidirectional data bus. The controller receives an output signal, determines an occupancy state for the associated defined area, and controls lighting devices in the area to be turned on and off in accordance with the determined occupancy state.
