  1. Automated Home Access Using RFID By: Harrizon Sanchez Travis AFB, California

  2. Overview • Background • Project Summary • Phidgets RFID reader • Electronic Door Strike • Powerbolt 1000 Electronic Deadbolt • Control Circuit • Circuit Diagrams • Conclusions

  3. Background • Never used RFID before • Lots of material available on line • Wanted to learn new concept • Ideas for RFID application • Pet identification • Supply chain management • Passport protection • Access control

  4. Project Summary • Build a RFID Control Box • Use a Phidgets RFID reader to detect tags • Use DPDT Relay to activate electronic strike & deadbolt • Modify control circuit of electronic deadbolt • Use laptop to control access to the door

  5. Phidgets RFID Reader • Reads tags brought within 3 inches of the reader • Reads any tag with EM4102 protocol • On-Board LED • Board connects directly to a computer’s USB port • Drivers and source code for sample application

  6. Output Screen for the Software

  7. Electronic Door Strike • Mortise Type • Accepts variable AC or DC voltage • Power Source • 16VAC Power Supply • rated at 10VA

  8. Powerbolt 1000 Electronic Deadbolt • Control box has open and close switch that made the hack easier • Has an option for standard key in case batteries die • Automatic door locking after 30 seconds

  9. Control Circuit • Close & Open Switch • 5V Reed Relay • Electrolytic Capacitor • Resistor

  10. Circuit Diagram

  11. Conclusions • Correct/updated drivers for RFID reader • Have the latest library for RFID reader before compiling your code • Beyond just opening door • Tags need to be compatible / same protocol before they can be recognized by a specific RFID reader
