Accident detection and alert system using arduino

Abstract

Initially the GPS continuously takes input data from the satellite and stores the latitude and longitude values in Arduino. If we have to track the vehicle, we need to send a message to GSM device, by which it gets activated. It also gets activated by detecting accident on the Vibration Sensor connected to vehicle. In Parallel, it deactivates GPS with the help of relay. Once GSM gets activated it takes the last received latitude and longitude positions values from the arduino and sends a message to the particular number or laptop which is predefined in the program. Once message has been sent to the predefined device the GSM gets deactivated and GPS gets activated.
