OPEN “smart” shelves system is equipped with light sensors allowing for a detection of changes in quantities of products on them and their distribution across the surface, easily assessing the amount of goods left and how they are positioned on shelves. If a shelf needs restocking, the system sends a notification on the current status in the system and then a notifications to the employee’s smartphone or e-mail address may be set so they can outlay or order goods.
There are other “smart” shelf solution in the market, including those based on weight sensors. Major disadvantages of such solution are high installation costs and possible miscalculations. Such smart shelves can detect that the product is out of stock or display the amount left but they can’t identify the wrong product on shelf from the same product line and with identical weight. Moreover, this system is not applicable with every product category, for example, if a product is too light the sensor may not detect it at all or after a long period of heavy product storage (beer category or dog food) the equipment needs calibration.
