3. Background & Motivation
 Tracking and navigation system were first
utilized for transportation business . But
now a days as innovation developing at a
quick rate the usages of tracking device are
manies.
 In Bangladesh tracking system are mainly
used for transport companies , courier
companies , traffic operators.

4. Background & Motivation (contd..)
 Now a days in all over the world every in 40 seconds a child become missing or
kidnapped . This microcontroller based task called child tracking system which
made numerous miracles in the security of the kid.
 A national work ship titled “Missing Child Alert”(MCA) featured that 200,000
children missing cases are recorded in South Asia consistently and around
20,000 of that number are young stars from Bangladesh . The purpose of the
child tracking device is to ensuring security of this children.
 Probably the most terrifying ordeal for parent is to lose sight of their kid .
Recently all over the world crime against children is increasing at a higher rate
and it is high time to offer safety support system for the children going to
school.

5. Background & Motivation (contd..)
 The use of GPS and GSM technologies
allows the system to track object and
provides the most up to date information
about kids.
 Achieving maximum productivity with
minimum wasted effort or expense for
tracking the children who is outside home.
5

6. Background & Motivation (contd..)
 The fundamental concept of this system uses mobile phone
application with the help of a micro controller . Now a days 80% of the
pepole in all over the world usages mobile phone .The major issue of
child tracking system can be solved with the help of a mobile phone.
 Upgrading this setup is easy which makes it open to future
requirement which also makes it more efficient.

7. Objectives
 The main objective of this project is to ensuring security to every child
by developing a simple cost effective device
 This tracking system can be a good solution for decreasing the
number of missing children and child trafficking in Bangladesh .
 User friendly, easily accessible monitoring system.
 Literature review on microcontroller based tracking system.
 Design and implementation of a child tracking system.

8.  The tracking system for children
will track and monitor the location
of the children.
 The parent can monitor their
children location through a simple
SMS and can see the exact
location.
 These child tracking system are
ideal for the parents who are in
office or if the children is outside of
home.

Child Tracking System.

9.  The whole system is divided into three main sub systems . GPS , GSM, and
Arduino subsystem.
 GPS is used for describing the position of the children in the form of longitude &
latitude.
 This longitude & latitude is received by the GSM. And GSM send this information
to the trackers mobile number via message.
 Arduino chip is used software or IDE (Integrated Development Environment) that
written in computer, used to write and upload computer code to physical board.
And Google Map is used to improve the accuracy of this system.

10. Child Tracking System ( Contd….)
Google Map improves the accuracy of
the tracking location of children So it
offers the additional functionality which
requires high accuracy . Extract location
of the children such functionality requires
high , accuracy with GPS module
coordinates , validity of the system
72.2% and with Google Map validity of
the system 95%.

compatible, flexible and
breadboard friendly
microcontroller Board.
 Input voltage varies from 7v to
12v.
 It has 14 digital pins, 8 analog
pins, 2 reset pin and 6 power
pin.

19. Implementation (contd..)
 GPS Module U-Blox NEO-6M:
 Cost effective,high performance GPS
Module.
 It has a ceramic patch antena,an
 on-board memory chip and a backup
battery.
 The input voltage is between 3.3-5 v.
 It has the capability to track upto 22
satelites on 50 channels.
