1. INTELLIGENT STUDENTS
TRACKING SYSTEM IN CAMPUS
RF

2. abstract
• With the rapid increase in the number of institutions as well as number of students in every
institution, it is very difficult to monitor whether the students are attending the classes as per the
time table or not.
• Even the students are in the campus but not present in the classes during the class hour.
• In the existing system, presence of students in the class is being monitored by taking attendance
manually in the class.
• In this paper, we propose an intelligent student tracking system based on RF wireless network.
• The proposed system reads the RF transmitter and RF receiver, and then sends it to admin mobile
node by a custom wireless protocol on the Bluetooth 2.4ghz channle.
• Here each and every student is assigned with different RF tags with individual tags numbers and
the RF readers are placed in campus at different locations which identifies the persons coming to
that location by reading RF tag numbers of the students and intimates to the control room about
their status.

3. introduction
• As the number of institutions as well as the number of students in each
institution is increasing it is harder to monitor the presence of students in
class during the class hours.
• In existing system students should be monitored continuously whether they
are attending the classes or not manually in the classes by means of taking
attendance but there are many chances of student escaping from different
ways.
• In the proposed paper, an intelligent campus student tracking system will be
designed and implemented based on the RF and Bluetooth network which
keeps track of where the student moves with in the campus.
• The system reads the RF tags data through RF receiver, and then sends it to
mpbile app node by a custom wireless protocol using Bluetooth.

6. DESCRIPTION OF REGULATED POWER
SUPPLY
Each of the block is described in
more detail below-
Transformer-steps down high
voltage AC mains to low voltage
AC.
Rectifier- Converts AC to DC ,but
DC output is varying.
Smoothing- smoothens the DC
from varying greatly to a small
ripple.
Regulator-Eliminates ripple by
setting DC output to a fixed
voltage.

7. Component Description
Arduino Uno
Arduino Uno is an ATmega 328p
Microcontroller based prototyping
board. It is an open source
electronic prototyping platform
that can be used with various
sensors and actuators.
Arduino Uno has 14 digital I/O pins
out of which 6 pins are used in this
project.

8. LED
• LEDs are semiconductor devices. Like
transistors, and other diodes, LEDs are
made out of silicon. What makes an LED
give off light there are the small
amounts of chemical impurities that are
added to the silicon, such as gallium,
arsenide, indium, and nitride.
• When current passes through the LED, it
emits photons as a byproduct. Normal light
bulbs produce light by heating a metal
filament until it's white hot. Because LEDs
produce photons directly and not via heat,
they are far more efficient than incandescent
bulbs.

9. PCB
 Printed circuit board(pcb) mechanically supports and electrically connects electronic
components using conductive tracks,pads and other features etched from
cooper sheets laminated onto a non-conductive substrate. PCBs can be single
sided(one copper layer),double sided(two copper layers) or multi layer(outer and
inner layers).

10. REGULA
TOR:
A voltage regulator is an electrical regulator designed to automatically maintain
a constant voltage level. we are using LM7805 regulator in this project .it may be used to
regulate one or more AC or DC voltages .

11. rf module
• Transmission through RF is better than IR (infrared)
because of many reasons.
• Firstly, signals through RF can travel through larger
distances making it suitable for long range
applications.
• Also, while IR mostly operates in line-of-sight mode,
RF signals can travel even when there is an
obstruction between transmitter & receiver.
• Next, RF transmission is more strong and reliable
than IR transmission.
• RF communication uses a specific frequency unlike
IR signals which are affected by other IR emitting
sources.

13. CONCLUSION
• As seen from the results, with the intelligent Campus Student Tracking
System, we can track and maintain a history of the student’s movement
in various locations within the campus, during class hours.
• This in-turn helps in improves the attendance of students in class room
during class hours.
