So, whenever an unauthorized person enters the vehicle a message is sent to the owner of the vehicle.

In accident identification system a microcontroller is placed to identify the amount of damage caused to a vehicle in case of accident. This happens by a dedicated acceleration identification IC. In case of accident, the change in the acceleration is assessed and the amount of damage calculated. After this the alarm signal is transmitted through an RF transmitter if the accident is found to be very high.

An RF receiver is placed at any station (hospital or police station) or if needed can be placed at regular intervals in the highways and the alarm signal can be received by them whenever there is an accident. Immediately it can alert the concerned authorities to take necessary action.
