THEFT INTIMATION OF THE VEHICLE OVER GSM BY SMS WITH USER PROGRAMMABLE NUMBER FEATURES.INTRODUCTIONThe main intention of this project is to track our vehicle if any theft takes place.Location of car would be continuously monitored using GPS and GSM technology. A mobile phone is used which receives current location of vehicle in the form of text message.We can shut off engine of car from any remote location by sending a sms to gsm module.TOOLS

Domain Embedded systemsSoftware Arduino 1.0.5Communication GSM ModuleLocation device GPS Module Microcontroller Board Arduino UNOReceiver Mobile phone, SIM CardFrequency band GSM (800/1900 MHz)

WORKING OF PROJECT

The system has a sensor connected to the ignition which keeps track if it is ENABLED/DISABLED. When the car is in locked state and the ignition is turned on or ENABLED then the theft case is invoked.When theft happens the system sends an SMS to the Owner in the following formatCar THEFT Location: .User upon receiving the text message can reply with an SMS with following options Retrieve location (system replies with the location) Enable Ignition (Ignition is turned off via the relay in ignition system) Disable Ignition (Ignition is turned on via the relay in ignition system)The 12 Digit Security Code is unique to each manufactured system.

GSM MODULE

GSM MODULEThe GSM network is used to provide communication from one place to another.The GSM module consist of a mobile station(ME and SIM).The module we use here is SIM900A.It can work on 800/1900 MHz frequencies band.The baud rate is configurable from 9600-115200 through AT command.The Modem is coming with RS232 interface, which allows you to connect to the PC as well as Microcontroller.The commands that are used to provide communication are called AT commands.The AT commands specifies the GSM technology and are related to SMS service.

AT commandsAT commandsare used to control MODEMs. AT is the abbreviation for Attention. These commands come from Hayes commandsthat were used by the Hayes smart modems. The Hayes commands started with AT to indicate the attention from the MODEM. The dial up and wireless MODEM devices that involve machine to machine communication) need AT commands to interact with a computer. These include the Hayes command set as a subset, along with other extended AT commands.All command lines must start with "AT" and end with a carriage return character.Types of AT Commands:-1) Basic:-A capital character followed by a digit.Syntax:-ATWhere = command & = Argument2) S-parameter:-Syntax:-AT = Where = is the index of the s-register to set & = is the value assigned to it(it is optional).3) Extended:-AT commands that start with "+". All GSM AT commands are extended commands.

Syntax:-AT+ Where = command.In our project we use extended AT Commands & in extended AT commands we use mainly 3:-1) ("AT+CMGF=1"); This Sets the GSM Module in Text Mode.("AT+CMGS=\"+9197xxxxxx\"\r"); This is used to set the no. to which sms to be send.3) ("AT+CNMI=2,2,0,0,0"); AT Command to receive a live SMS.

GPS MODULE

GPS MODULETo find location by using longitude and latitude data.The GPS Module we use here is SIM28M.SIMCom presents a small, high performance and reliable assisted GPS module-SIM28M. This is designed with high sensitivity navigation engine, which allows you to achieves the industrys highest levels of sensitivity, accuracy and Time-to-First-Fix(speed of positioning) (TTFF) with lowest power consumption.Support AGPS.

ARDUINO UNO

ARDUINO UNOIt has flash memory of 32Kb.Clock speed of 16Mhz.Operating voltage is 5Volts.An easy USB interface.14 digital pins and 6 analog pins.DC current per I/O pin is 40mA.Its RAM size is 2048 bytes.

ADVANTAGESAlert message to mobile phone for remote information.Mobile number can be changed easily.We can shut off engine from any location.Password protected system.Real time vehicle tracking.

APPLICATIONIt can be used as an alternative to traditional car alarm.Can be used by police to track location of stolen vehicle.It is being used as a trap by police to catch car thieves.It can be used by taxi operators to direct nearest taxi towards costumers.

FUTURE SCOPEWith the help of high sensitivity vibration sensors we can detect accidents & then send an alert sms to family.We can increase the accuracy up to 3m by increasing the cost of GPS receivers.System can also be used in banks to lock bank locker via sms while unauthorised person is trying to unlock it.
