The present disclosure generally relates to system and methods for determining the available storage capacity of an enclosed space using visible or near-visible light. A system may utilize one or more light sources and one or more light sensors to sense objects that occupy a physical space. The light sources may be used to produce and radiate light through the space towards the one or more light sensors, which may then measure the intensity of the radiated light received at the sensor. The result of this measurement may be compared against a baseline measurement of the intensity of the received light when the space is completely unoccupied, with the difference between the current measurement and the baseline being proportional to—and with some processing, directly indicates—the amount of the intervening space that is occupied by physical objects.
