2.  Background  Problem Statement  Solution Statement  Array Placement Concept  System Overview  Sensors Evaluated  Mechanical Design  Original and Final  Assembly  O-ring Gland Design for PIR door  Verify O-ring Seal  Electrical Design  Microcontroller Circuit Board Schematic  Microcontroller  Actuator Subsystem  CAN Communication Subsystem  Software Design  States, Inputs, and Outputs  State Diagram  Schedule  Cost of Engineering and Design  Questions

3.  Deployed Vehicles Unattended  Vehicles tampered with unattended  A vibration sensor is currently employed  Wide open spaces and wind gust  Not immune to vibrations due to wind  False alarms  Determine an actual threat from wind gusts

4.  Check Feasibility of Different Sensors  Discrete Package  Robust  Water Proof  Easy to Replace  Sensitivity  5 Volt  Max current 0.577 A  Detection is directly under the Vehicle

5. Sensor 5 Volt Water Proof Robust Easy to Replace DiscreteSensitivity PIRXXXXXX Ultra-SonicXXXXX Pitot TubeXX Gust DetectorXX PIR Maxbotix LV-EZ0 Pitot Tube Pressure Sensor Freescale MXP2010 Gust detector using a ping- pong ball and optical sensor

6.  To design a system that uses a Passive Infrared Sensors (PIR)  An array of PIRs shall be installed on the under carriage  Create a detection envelope directly under the vehicle  The sensors will only be deployed when the alarm is activated

7.  Person crawls under vehicle to tamper with it  PIR detects persons movement under vehicle  Sends threat verification signal through the CANbus  Threat is detected

8. These beams are not actual but a visual concept of the array and detection envelope
