Vehicle to vehicle safety device - an ease for safe driving

This research is basically on an electronic device which can be used at the time of emergency while driving a vehicle. It has embedded the concept of wireless communication i.e. Zigbee and GSM and many other sensors by the help of which immediate help can be delivered to the person who has met with an accident. The overall structure is based on the AT89S52 microcontroller. Also the key role of DTMF has been implied by the help of which appropriate user can control the security options of vehicle if it is theft. Research content uses the technology of Zigbee for the transmission of message to the other vehicle in the time of need of their help as well as for serving the prospective of safe and sound driving the functions like drivers alcohol detection, vehicle speed slowing and automatic car lock with collision detection is used. The GPS is also being used here for finding the exact car location so that it can be found if lost.
