  1. Smart Kitchen Suppakrit Forbes Chatchayanusorn Charles Christopher Onyeama Nachiket Shelgikar Saravana Sivasankaran

  2. How it works! • System • Smart phone/ PDA with Docking Station • RFID reader reads tags off the products in the kitchen and updates the ‘status’ of the kitchen. • Smart phone/ PDA generates a shopping list based on ideal stock and current kitchen status • Assumptions • All the products will be RFID tagged replacing currently used UPC Barcodes

  3. Architecture Block Diagram • RFID sensors detect the tags using RF and sending data to CPU via Ethernet interface • CPU shall handle the database immediately • CPU shall wait until the device requests data and starts synchronize via Bluetooth interface

  4. Use Cases • Check Grocery List • Modify Grocery List • Manually Synchronize Grocery List • Automatically Synchronize Grocery List

  8. Risks • Read multiple tags • Too close to each other or touching • Tags in different orientations • Buffer overflow during the communication between the RFID reader and the Gumstix • Loss of packets • One RFID Reader • Cannot Identify direction of motion • Cannot effectively make out when the product leaves the house • Two RFID Readers • Direction of Motion • Have both of them synchronized to identify products coming in vs. going out of the house • Radio Interference

  9. Risks Mitigation • Handled by having antennae in different directions to have maximum surface area exposed to antenna • Have header and footer checks for the packet data
