Abstract
The present invention provides a system comprising an occupancy sensor for sensing occupancy of an area, able to activate upon sensing occupancy of the area, maintain activation when sensing continuing occupancy, to include settings therefor, and to enable self-adjusting of the settings. It includes an infrared sensor section, able to passively sense occupancy and activate a signal, continue to activate upon sensing continuing occupancy, and enable separate processing of the settings. It also includes an ultrasonic sensor section, able to actively sense occupancy, activate a signal upon sensing continuing occupancy, and enable separate processing of the settings. The occupancy sensor is able to activate when the infrared sensor section senses occupancy, and to maintain activation when either the infrared sensor section or the ultrasonic sensor section senses continuing occupancy of the area. The infrared sensor section signals and the ultrasonic sensor section signals are each independently formed and activated.
