Abstract: A motion sensor includes a sensor element to sense a motion, and a controller communicably coupled to the sensor element. The controller is configured to set a detection sensitivity of the motion sensor to a maximum setting of the detection sensitivity. The controller is further configured to decrease the detection sensitivity of the motion sensor upon a detection of the motion until the motion is undetectable by the motion sensor at a decreased setting of the detection sensitivity. The controller is further configured to increase the detection sensitivity of the motion sensor until the motion sensor detects the motion at an increased setting of the detection sensitivity and to set the detection sensitivity of the motion sensor to a new setting based on the increased setting.

Abstract: An imaging sensor determines an influence of artificial light from one or more artificial light sources and an influence of natural light in an area associated with a lighting system. On the basis of the influence of the natural light and the influence of the artificial light, the imaging sensor determines the location of the one or more artificial light sources with respect to the location of the imaging sensor.

Responsively, the imaging sensor associates at least one artificial light source of the one or more light sources and occupancy sensors corresponding to the at least one artificial light source with the allocated area of influence.
