A Smart system for Four wheelers

Abstract

A total security system based on Global System for Mobile, is developed to prevent a car from
theft. This consists of ARM7 controller, ARM7 processor is one of a family of CPUs based on
the RISC (reduced instruction set computer) architecture developed by Advanced RISC
Machines (ARM).GSM, an alcohol sensor and seat belt detector. When anyone wants to open
the door forcibly, the switch gets into open condition, which cuts ignition and a text message is
sent to the owner’s mobile using vehicle GSM module and sends it to the owner. if the driver
fails to fasten the seat belt and if driver has consumed alcohol text message is sent to the
owner’s mobile using vehicle GSM module. An ignition off feature is also used for more
prevention. Further the connection to fuel injector of the car is stopped so that unauthorized
person cannot start thevehicle anyhow.
