Introduction
Most of the times we may not able to find accidents because we don’t know when accident will happen, in order to give treatment for injured people first we need to know that accident indication by sending to your related one when your there inside of vehicle.

Atmel AT89s52 is a powerful microcomputer, which is a highly flexible and cost-effective .
In Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning.
In power-down mode saves the RAM contents

Max 232

•The MAX232 is an integrated circuit that converts signals from an RS-232 serial port to signals suitable for use in TTL compatible digital logic circuits
•A standard serial interfacing for PC, RS232C, requires negative logic, i.e., logic '1' is -3V to -12V and logic '0' is +3V to +12V. To convert a TTL logic, say, TxD and RxD pins of the uC chips, thus need a converter chip.

GSMGSM (Global System for Mobile
communications), digital cellular technology used for transmitting mobile voice and data services.
GSM uses TDMA, which allows eight simultaneous calls on the same radio frequency.
It operates at either the 900 MHz or 1,800 MHz frequency band.

A GSM modem requires a SIM card from a wireless carrier in order to operate. GSM modems support a common set of standard AT commands.Reading, writing and deleting SMS messages.Sending SMS messages.Monitoring the signal strength.Monitoring the charging status and charge level of the battery.Reading, writing and searching phone book

RFID(RADIO FREQUENCY IDENTIFICATION)
RADIO FREQUENCY IDENTIFICATION uses a semiconductor (micro-chip) in a tag or label to transmit stored data when the tag or label is exposed to radio waves of the correct frequency.
