“…Additionally, unlike PIR sensors which are solely focused on detecting motion, these color sensors have demonstrated their ability to provide additional information about the space. Such capabilities include performing daylight detection by monitoring the solar heat gain of the space [23], being part of a feedback control loop aimed at optimizing light quality for human perception and comfort in the presence of changing ambient light conditions [24] as well as determining the spectral reflectance of an illuminated space as demonstrated in this paper. Further experiments are planned to explore the ability of these sensors to perform accurate occupant localization and tracking.…”

RGB color sensors are examined as an economical replacement for non-lighting based occupancy sensors such as PIR sensors and ultrasonic sensors. RGB color sensors are inexpensive and able to accurately detect and track occupants in an illuminated space by monitoring color shifts from background color distribution caused by occupants. By examining the temporal dependence of color shifts caused by small occupant movements, it is possible to avoid false occupancy/vacancy detections associated with other sensor types. Additionally, RGB color sensors provide information about the spectral reflectance of the illuminated space and this information can be used to compensate for spectral absorption properties of surfaces that alter the perceived emitted spectral power distribution (SPD) from the lighting. These changes may impact occupant perception and circadian performance.
