2011- Vermont Technical College Electro-Mechanical Senior Project Networked Advanced Vehicle Anti-Tamper & Alert System
2
Deployed Vehicles Unattended ARA designed a vibration sensing anti-tamper system Threats tamper while unattended Wide open spaces and wind gust Not immune to vibrations due to wind False alarms Determine an actual threat from wind gusts
3
To design a system that uses sensors to differentiate between wind and a real threat to the vehicle, that can be used in harsh environments, robust enough to withstand constant vibration and impact, and easy to maintain.

PIR sensors are detecting a change in radiation in its field of view Sensor is split into two half and the IR levels are compared between the 2 halves. If one side detects a higher IR radiation than the other side the output is pulled up or down The use of a lens give a wider field of view as will a greater comparator sensitivity
