1. A method of wirelessly detecting area changes, the method comprising:
- storing a plurality of predetermined thresholds in a memory, the plurality of predetermined thresholds comprising time of day, calendar day, and activity, wherein the activity is related to an estimated number of occupants within an area targeted by a wireless sensor;
detecting a change in the area targeted by the wireless sensor;
executing instructions stored in the memory, wherein execution of the instructions by a processor;
masks a portion of the targeted area by modifying a sensitivity threshold associated with the portion of the targeted area, wherein the masked portion of the targeted area is associated with a different sensitivity level than an unmasked portion of the targeted area;
determines at least two applicable thresholds out of the plurality of predetermined thresholds stored in the memory, wherein one of the at least two applicable thresholds includes the activity; and
determines that the detected change meets the at least two applicable thresholds;
wirelessly transmitting information indicating that the detected change meets the at least two thresholds to an associated controller, wherein the associated controller controls power usage of a device associated with the unmasked portion of the area targeted by the wireless sensor, based on the transmitted information; and
detecting a change in levels of red-green-blue light in the targeted area, wherein the determination that the detected change meets the two applicable thresholds out of the plurality of predetermined thresholds include;
verifying that the detected change in the levels of red-green-blue light is associated with a change in illuminance; and
determining that the change in illuminance meets the two applicable thresholds.

Abstract
Systems and methods for wirelessly detecting area changes are provided. Predetermined thresholds may be stored in memory. Each predetermined threshold is associated with a time of day, calendar day, and/or activity. The sensor may detect a change in the in the targeted area. The detected change is evaluated to determine an applicable threshold. Then it may be determined whether the detected change meets a predetermined threshold. If so, information regarding the change is wirelessly transmitted to an associated controller that controls light in the targeted area. The operation of the light may be controlled based on the wirelessly transmitted information.
