17. [1] [2] By: Joshua Hamilton Power Conditioning

18. Reasoning: • Advanced detection functions require power • Zero false positives • No unauthorized access • Cannot be powered externally • Safe must stay secure until maintenance Power Conditioning

19. Requirements of power source • Necessary 1 year lifespan with a goal of 2 • Cannot be tampered • Power detection sensors • Safely power the Arduino controller • Dependable Power Conditioning

20. Method • Modes of operation • Wake up sensors • Self powered vibration sensors • Low power design • Efficient overall design • No leakage Power Conditioning Fig. 1 Piezoelectric vibration sensor [3]

21. Implementation • Arduino Mega vs Arduino Pro-Mini • Piezoelectric wake-up circuit • Choice of battery • Lithium has highest power density • Sensitive to high temperature • May need a controller Power Condtioning

22. Conclusion • Test two types of batteries • Arduino backpack • Energizer e2* AA batteries Power Condtioning Fig. 2 Arduino backpack [4] * “E2 Datasheet”, Apr. 8, 2010. [Online]. Available: http://Energizer-L91BP-8-Lithium-Battery-8-Pack/dp/B0000DC4EL

24. [1] By: Arslan Majid [2] Creating the Interface

25. Use Labview to create a GUI • Display GUI on an external source (Laptop) • Goal- wireless Creating the interface [2]

26. Will carry out the following states of security system: Tasks to accomplish • Authorized user • Open container • Access contents • Close container • Do not tamper container • Security access • Allow transport • Reset alarm status • Check status report • Do not access contents • Maintenance access • Change power supply • Software/hardware upgrades • Do not access contents

27. Sample Menu • While on menu- • Sensors detect suspicious activity • Will display a warning if sensors set alarm off • Sub-menus corresponding to different states of security will also be displayed

28. Timeline

29. Budget

30. Utilize an array of sensors Low power / Sleep mode Optimize for small size Accept wireless input Provide alarm signal Conclusion
