Disclosed is a system for real-time measurement of inventory on shelves. The system uses light sensors placed in association with the inventory and the shelves to measure in real-time the removal/replacement of inventory from the shelves. When inventory is on the shelves, less light reaches the light sensors. As inventory is removed from shelves, the light sensors receive more light. The difference in light received generates as signal that can be measured, thereby allowing for determining inventory levels on each shelf. The system may be retro-fitted to existing shelving systems, thereby avoiding the cost of purchasing new shelving systems. The system can work on any shelving system, including gravity-feed roller shelf (GRS), flat shelves, and spring loaded pusher shelves, and is unaffected by usual temperatures found in retail establishments and can thus work in both refrigerated and unrefrigerated systems. Also disclosed are related methods.
