A system and method for tracking items may store in memory first association data reflecting an association between an item tracking device and a beacon device when the item tracking device is within a predetermined range of the beacon device. The item tracking device may correspond to a first item, and the beacon device may correspond to an area that contains multiple items including the first item. Furthermore, the system and method for tracking items may periodically transmit sensor data to a database. The sensor data may be transmitted to the database from the beacon device to provide information about an environment of a group of items from the multiple items within the predetermined range of the beacon device.
