System and method for auto-commissioning based on smart sensors
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. Further, the imaging sensor allocates a portion of the area as an area of influence of the imaging sensor based on a threshold change in luminescence of the area associated with switching on or switching off of the one or more artificial light sources. 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.
