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.
