Here in this project, we are build a embedded systems based vehicle accident alert system using GPS, GSM and shock sensors. Shock sensor is used to detect accident. So, when accident happens, this sensor will be active. And the information sends to microcontroller. At the same time,GSM module will also active which are interfaced to the same microcontroller. Through GSM the exact location of the accident location is obtained And through GSM module send a alert message to the register mobile number and police station. And information is send to the near Police Stations,family members, friends etc.
