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.
