Explanation of Project Background Project sections:
Programming Sensors Power Interface Time Line and project goals
Current safes offer no electrical security*.
No alarm when broken into. Bulky.
* = Other than electrical password entry

Reasoning: Advanced detection functions require
powerZero false positivesNo unauthorized access
Cannot be powered externally Safe must stay secure until maintenance
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
Method Modes of operation Wake up sensors
Self powered vibration sensors Low power design
Efficient overall designNo leakage
Fig. 1 Piezoelectric vibration sensor [3]
Implementation Arduino Mega vs Arduino Pro-Mini Piezoelectric wake-up circuit Choice of battery
Lithium has highest power density Sensitive to high temperatureMay need a controller
Conclusion Test two types of batteries

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