The project here is all about a CAR Automation & Security Control Interface, In this project we have planned to develop a CAR Automation & Security Control Interface.
CAR Automation & Security Control Interface for detecting an intrusion into a monitored area by an infrared detector. A Automation & Security Control Interface has a flee-standing intrusion detector.



 The

free standing intrusion detector has a transmitter coupled with a portable receiver to alert a CAR owner that an intrusion has taken place or occurred within a pre-set time period. The area under surveillance is monitored by an infrared detector which activates the transmitter upon the detection of abrupt differences in infrared radiation levels, associated with the presence of a warm body in an otherwise equilibrated environment.

 Auto

dialer system.  Remotely operated system using land lines. DISADVANTAGES:  Only one way communication.  Unable to take any local and immediate action.

In this security system we are sensing the human movements by means of IR sensors and alerting the security and the police simultaneously using gsm wireless networks. This system automatically gets turned on when the CAR gets closed this is mainly done by means of IR sensors.

 Two

way communication can send and receive messages.  Land line disturbances not involved.  No maintenance required.  Operates on any gsm network SIM card.  User friendly start up.

APPLICATIONS: •CAR Automation & Security Control Interface is used in Auto Monitoring in the all parts and systems of home. HARDWARE REQUIREMENTS

•PCB •MICROCONTROLLER •STEP DOWN TRANSFORMER 12V/500mA •VOLTAGE REGULATOR LM7805 •RECTIFIER DIODES 1N4001 •ELECTROLYTIC CAPACITORS •LCD DISPLAY •LEDs •SENSING ELECTRODES •OPERATIONAL AMPLIFIER •PVC WIRES •RELAY •IR Tx-Rx DEVELOPMENT TOOLS REQUIREMENTS •INTEGRATED DEVELOPMENT ENVIRONMENT •COMPILER, ASSEMBLER, SIMULATOR •EMULATOR, PROGRAMMER

We proposed a novel configuration for the sensors and a set of features that can be easily calculated by typical wireless sensor nodes based on low power microcontrollers (e.g. 8 bit ones).As it is a wireless based technique without the knowledge of the thief we can alert the security and the police station with the alert signal and the LCD display, also their exists a credit of switching on the system automatically. The future advancement that can be done in this project is that we can transfer a live video of about what is prevailing there using 3G technology.
