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
