This document presents a project to design a low-cost engine immobilizer system for vehicles using an Arduino microcontroller, GSM module, and ECU interface. The system will allow the user to stop and restart the vehicle remotely by sending text messages. A block diagram shows the connection of the GSM module, microcontroller, and ECU to the fuel injection system and engine. The document includes the existing immobilizer technologies, proposed work, simulation code, sample outputs, and timeline for the project.

REVIEW - 3
With the expansion of the internet in smart gadgets with the latest internet
technologies like IPv6, LTE, and 5G, the intelligence is embedded into the many
devices used in various application domains like: health, agriculture,
transport, defense, and energy sectors. The aim of embedded intelligence in a
machine through an application specific embedded microcontroller, sensor shields
integrated with signal conditioning and signal processing circuitry,
communication modules, smart power management system, is to interact with other
machines equipped with similar facilities, in the form of machine2machine (M2M)
communication.

4. ABSTRACT
The upcoming technology where machine to machine communication is possible
by deploying the intelligent sensors on machine for smart interaction. Internet of
things (loT) gives a wide scope in many application domains where number of
smart gadgets per person is increasing exponentially with time. The automobile
sector is also one of the application domain where vehicle can be made intelligent
by using loT. This paper presents the interface of Arduino Uno R3 development
board, sensor shield and smartphone. The proposed schematic is for car security
which gives the access of car through internet and GPS, to the owner of car, in
case car is stolen or damaged.

5. EXISTING WORK
Current Anti-theft system prevents the engine from starting without using vehicle’s
authorized key. This system uses a special digitally coded key or a Smart Key fob
having a transponder chip. This system is currently available in high-ended cars
such as BMW.

6. PROPOSED WORK
● The objective of this project is to design low-cost Engine immobilizer through
ECU- Microcontroller (Arduino UNO R3)-GSM interface.
● The main key features of proposed security system is to allow the user to stop
and restart the car at any desired instant by sending the messages: "stop the
car" and "restart the car".
