Project Background & Problem Domain
• Motor vehicle emission is a significant source of air pollutionaffecting both animals and the environment.
• There is no system is the world today that can automaticallymonitor, record, query and analyze real time emission data frommultiple vehicles.
• The system developed can perform all such tasks and help reduceenvironmental pollution to a greater extent.
A Frequent, Accurate, Detailed & User Friendly
Emission Testing Mechanism Is Therefore Needed.

Conclusion
• Difficulties
Conclusion – Cont.
• Future Enhancements
• Read vehicle’s speed along with the gas ppm.
• Display real time emission performance graphically.
• Automatically suggest repairs, send warnings.
• This system can be used as an all-in-one replacement for
• Car video/sound system
• GPS navigation
• Internet access
• Security System
Therefore, cost of this system can be easily covered.
