 ACKNOWLEDGEMENT

At the outset, I would like to thank and praise the almighty god who has given me
wisdom and knowledge to complete my mini - project as a part of my curriculum.

We would like to extend my heartfelt thanks to our Dr. P.V. Krishna Murthy, Principal,
and Dr.A.SRINIVASA RAO, Associate Prof and Head of the Department, Electronics and
Communication Engineering, Annamacharya Institute of Technology and Sciences, Hyderabad,
for giving us the permission to take up this project. We would also express our gratitude to my
internal guide Dr. A. Sreenivasa Rao, M. Tech ,Ph.D,Head of the Department, Dept of ECE who
has given us his valuable suggestions.

Last but not least, we would like to thank our Mini project coordinator M.RAVI
M.Tech, Asst Prof., Dept of ECE all the staff members of Annamacharya Institute of
Technology and Sciences, especially the faculty of Electronics and Communication
Engineering Department whose constant support, encouragement and co-operation helped us to
complete our Mini-Project smoothly.

Once again, we thank one and all who are associated with us directly or indirectly for
completing this project.

MINI-PROJECT ASSOCIATES
 ABSTRACT

The fastest growth of technology has made our lifestyle Comfort. The technology also

increased the traffic risks and the road accidents take place frequently which causes huge loss of life

because inadequate of emergency facility our project will help this displacement. The project

concludes when a vehicle meets with an accident, the vibration and IR sensor will analyze the signal

and this signal to Arduino. The notification is sent through GSM module the location of the accident

is gathered with the help of GPS module, to notify police control room or a rescue team.

So, the police or rescue team can immediately trace the location through the GPS Module,

after receiving the information. Then after confirming the location necessary action will be taken And

Video of the accident can be live streamed or can be stored with the help of camera. The aim of this

work is to automatically detect an accident and alert the rescue team or control station.
