Lessons Learned

Conclusion

Everyone gained a wealth of knowledge working on this project. The group gained hands on experience with Wireless Communications. We applied what we learned in our communication courses to help complete the project.

The main goal of this product is to automatically informing EMS whenever a vehicle is involved in an accident. The idea is to implement a system that will send an SMS message to the Emergency Medical Service (EMS) shortly after the airbags are deployed. When the SMS message is received, EMS will be able to track the vehicle with the help of the

Final Prototype

EMERGENCY CALLING SYSTEM ImpactA mechanical switch senses when there is a mass shift that closes an electrical contact (activated), telling the sensors that a crash has occurred.

GPS Reading

This picture shows the received signal quality for each of the visible satellites. The greater the number of visible satellites, the more accurate the GPS data becomes.

The group was able to work successfully as a team and complete the project. Each team member provided different skills to help finish the project before the deadline.
