This document describes an IOT based automatic vehicle accident detection and rescue system. The system uses an accelerometer sensor to detect accidents and a GSM module to send alerts about the location to guardians and rescue teams. The aim is to reduce loss of life from accidents by reducing response times. When an accident is detected via the accelerometer, the microcontroller sends a message with location data from the GPS module via GSM to emergency responders. The system uses components like an Arduino, sensors, displays and wireless modules to automatically detect accidents and alert help.

3. Introduction
 The rapid rise of technology and infrastructure has made our lives easier. The high
demand of automobiles has also increased the traffic hazards and road accidents.
Life of the people is under high risk. The delay in reaching of the ambulance to the
accident location and the traffic congestion in between accident location and
hospital increases the chances of death of the victim.
 To overcome this problem our automatic ambulance rescue system comes to the
rescue. This proposed IOT based accident detection system helps to reduce the loss
of life due to accidents and also reduces the time taken by the ambulance to reach
the hospital. This automatic ambulance rescue system project is useful in detecting
the accident.

4. Aim of the Project
 the aim of my project is To detect the accident there is accelerometer sensor present in
this rescue system and the GSM module included sends messages about
 the location to the respective guardian and rescue team. With the help of
accelerometer sensor signal, a severe accident due to an obstacle can be recognized.
Microcontroller used, sends the alert message through the GSM module including the
location to guardian or a rescue team. So, the emergency help team can immediately
trace the location through the GPS module, after receiving the accident location
information, action can be taken immediately.
 This accelerometer based accident detection system is powered by Arduino mega
microcontroller it consists of display, accelerometer sensor, GSM module and alarm.

5. Methodology
 In a block diagram a step down transformer is used to convert the supply from 230v to 9v.
 A bridge rectifier is used to convert the ac into dc to operate the function. Regulator to get the
stabilized wave form a Zener diode is used to get the pure dc wave form.
Accelerometer(ADXL335) is device that measure the vibration/acceleration of motion. The force
caused by vibration or a change in a motion the piezo electrical device experience force which
produce an electric charge which measure by accelerometer that says about the disturbance of
vehical.
 In accelerometer MCP3208 ADC is used to convert analog signal into digital signal as an input to
use.
 Arduino mega2560 micro controller is a controlling device. It is 8bit microcontroller which
contain 40 pin Ic. (each port consist 8pin .) to get desired function we programed in c language .
It based on cmos technology which consume low power. microcontroller desiged with static
logic for operation down to Zero frequency.

6. 16x2 LCD Display: An LCD (Liquid Crystal Display) screen is an electronic display module
and has a wide range of applications. A 16x2 LCD display is very basic module and is very
commonly used in various devices and circuits. A 16x2 LCD means it can display 16
characters per line and there are 2 such lines. In this LCD each character is displayed in 5x7
pixel matrix. The 16 x 2 intelligent alphanumeric dot matrix display is capable of displaying
224 different characters and symbols. This LCD has two registers, namely,
Command and Data. (2) GSM - MODULE : GSM Module SIM900A
Modem is built with Dual Band GSM-based SIM900A modem from SIMCOM. It works on
frequencies 900MHz. SIM900A can search these two bands automatically. The frequency
bands can also be set by AT Commands. The baud rate is configurable from 1200-115200
through AT command. SIM900A is an ultra-compact and wireless module.
(3) GPS MODULE : GPS Module NEO-6M module series is a family of stand-alone GPS
receivers featuring the highperformance ublox 6 positioning engines. These flexible and
cost-effective receivers offer numerous connectivity options in a miniature packa
