Abstract: A system and method is provided for inventory replenishment notification. The inventory replenishment system includes a plurality of bin monitors. Each of the bin monitors is coupled to one of plurality of inventory storage devices, with each of the plurality of inventory storage devices including a primary bin and a reserve bin. Each of the bin monitors includes a sensor and a transmitter. The sensor monitors for when the reserve bin is accessed to replenish the primary bin. The transmitter sends this bin replenishment information to an inventory control system. The inventory control system can then automate the ordering of replacement inventory to replenish the reserve bin. Thus, the inventory replenishment notification system can ensure that sufficient inventory is always available at the inventory storage device.
