Abstract: A universal multifunction sensor having multiple optical designs and providing a plurality of parameter sensors in one sensor module which can interface with and control operation of one or more processor control systems in an occupied space networked environment. The universal multifunction sensor comprises a passive infrared occupancy sensor and an ambient light sensor. A common network communications and control processor coupled to a common communication transceiver are shared in common by the occupancy sensor and the ambient light sensor, such that the multifunction sensor can interface with and control operation of one or more processor control systems in an occupied space networked environment.

Abstract: A multifunction sensor provides a plurality of parameter sensors in one sensor module which can interface with and control operation of one or more processor control systems in an occupied space networked environment such as a commercial building. The multifunction sensor comprises at least an occupancy sensor, an ambient light sensor, and a temperature sensor. A common network communications and control processor is coupled to a common communication transceiver, and are shared in common by the occupancy sensor, the ambient light sensor and the temperature sensor, such that the multifunction sensor can interface with and control operation of one or more processor control systems. A plurality of the multifunction sensors are placed at different locations throughout the building.

Abstract: A multifunction passive infrared occupancy sensor functions as an occupancy sensor for security systems and also as an occupancy sensor for energy management control systems. The occupancy sensor comprises at least one segmented infrared lens array wherein the segments of the infrared lens array establish different optical lobes in the field of view of the occupancy sensor. At least one pyroelectric infrared detector is positioned at or near the focal point of the segmented infrared lens array, for detecting movement of infrared sources within the field of view of the occupancy sensor and producing an output signal representative thereof. A processing means analyzes the output signal of the detector for security detection purposes by detecting changes in the output signal greater than a given security threshold.
