Power Conditioning
By: Joshua Hamilton
POWER CONDITIONING

Reasoning:
 Advanced
detection functions require power
 Zero
false positives
 No unauthorized access
 Cannot
be powered externally
 Safe must stay secure until maintenance
POWER CONDITIONING

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

Method
 Modes
of operation
 Wake up sensors
 Self
 Low
powered vibration sensors
power design
 Efficient
overall design
 No leakage

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
