Abstract

Examples provide a shelf location detection system. A shelf is supported by a shelf support arm engaging a notch in a smart shelf support member having a stack of resistors in series within the interior of the shelf support member. A plug on the support arm removably couples to the notch. A sensor detects a change in voltage across at least one resistor in the resistor stack. A location of the shelf on the smart shelf support member is determined using the detected voltage change. A controller on the smart shelf support member transmits the location to a controller on each accessory device on the shelf. The shelf can further include a plurality of resistors connected in series. The accessory device detects changes in voltage through the plurality of resistors and generates an estimated position of the accessory device on the shelf using the change in voltage data.
