Smart Bag

The Smart Bag is a very innovative and helpful project that uses RFID Technology [1] for identifying books / items smartly. The Radio Frequency Identification sensor uses a reader to get information about the item from a tag attached to it. Smart Bag initially used this technology. Technologies or devices which are used in development of The Smart Bag are RFID Sensor, HX711 Load Cell Sensor, NodeMCU, Arduino, and GPS. The Books / items canbe identified by using RFID tag and it will store the count of books / items to its memory and matches the items according to schedule. The circuit for communication comprises of NodeMCU and RFID receiver in which passing of messages / alerts, reading of books / item isdone. When the books / items are placed inside the bag, the RFID receiver reads the RFID Tagand sends the Books / items in the bag to the NodeMCU [2]. The NodeMCU compares it with the schedule list. If any book / item is missing then the NodeMCU generates an alert of missingbooks / item. The smart bag has GPS function also, which sends the Real-time Location of a Bag or a Kid to the Guardian or Parents. Initially, this project is for those small kids who regularlygo to school.
