Query: Vehicle Intrusion And Theft Control System Using GSM and GPS -- An
  advance and viable approach   This paper presents a novel approach towards the designing and development of
a feasible and an embedded vehicle intrusion and theft control system using GSM
(Global System for Mobile Communication) and GPS (Global Positioning System).
The proposed system uses GSM technology as one of the distinguishing building
blocks of the system. A GPS module Holux GR89 is used to trace the position of
the vehicle and Mercury Switches are used to collect analog data continuously,
in case of an intrusion, variations will be observed in sensors reading.
Continuous readings from sensors are collected on to the microcontroller
constantly and on the basis of those readings decision is taken whether an
intrusion is made or not and in case of an intrusion a message from a
predefined set of messages is generated to the owner of the vehicle and on
reception of the message, the owner will have the luxury to take an action via
an SMS either to lock the gears of the vehicle or seize the engine of the
vehicle from a far-off place. A relay is used to control gears and engine of
the vehicle while working with the microcontroller. A prototype system was
built and tested. The results were very positive and encouraging.
