Reasoning: Advanced detection functions require power Zero false positives No 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 design No leakage Fig. 1 Piezoelectric vibration sensor [4]
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
Conclusion Test two types of batteries Arduino backpack Energizer e 2 AA batteries Fig. 2 Arduino backpack [1]
