This paper is to develop a MEMS accelerometer and GPS tracking system for accidental monitoring. The system consists of an accelerometer, microcontroller unit, GPS device and GSM module, Temperature sensor. Micro Electro Mechanical System (MEMS) is a highly sensitive sensor and it indicates the position of an accident that is in which direction vehicle is tilted. When there is an accident, the Global System for Mobile (GSM) module will send SMS to the main server that is operating station and family member. the main server locates the accident spot, search the nearest hospital of that accidental area and give the information to the Ambulance driver about an Accident by using hospital unit so that the Ambulance will reach at the accident spot in time. Global Positioning System (GPS) is used to detect an accidental spot by using NMEA format and Micro-Electro-Mechanical System (MEMS) Accelerometer is used to locate the tilted position of vehicle and give this information to the microcontroller, Microcontroller sends this information to the main server by using Global System for Mobile Communication (GSM) Technology. Accidents have become a Big problem in Various countries and it happens because of drunk driving, riding with no helmet, riding without sufficient sleep, break problem of the vehicle, the clutch problem of the vehicle, etc. This project is about a system which is developed to automatically detect an accidental spot and give SMS to the main server and family member, the main server gives this information to the nearest ambulance driver by using hospital unit.
