This project combines a GPS module and PIR sensor to geotag locations where movement is detected. The GPS module tracks the location of objects, while the PIR sensor detects movement within a 5m radius. When the PIR sensor detects movement, the microcontroller reads the GPS data to geotag the location on a 16x2 LCD display. This allows tracking locations where motion occurs for applications like security, navigation, and archeological surveys.

2. AIM OF THE PROJECT
This project intends us to geotag a
particular location in accordance with
movement detection by using GPS module

4. DESCRIPTION
The project deals with a GPS module and a
PIR sensor.
The GPS module is a satellite based system
and tracks the location of the objects.
The PIR sensor is an infrared radiation based
sensor .
It detects the movement of the objects within a
radius of 5m.

5. MICROCONTROLLER
 The microcontroller used
is AT89C52.
 This is an 8 bit
microcontroller.
 It has a 8k of
reprogrammable flash
memory.

6. GLOBAL POSITIONING SYSTEM(GPS)
 The GPS is a satellite-based system.
 GPS works in any weather conditions,
anywhere in the world,24 hours a day.
 The GPS gets the longitudinal and
latitudinal value of the human location.
 The GPS receiver receives the longitudinal
and latitudinal value.

7. STRUCTURE OF GPS
The gps consists of three
parts. They are
 Space segment
 User segment
 Control segment
Space segment:
 This segment consists of the
satellite system
 These helps us to locate the
position by broadcasting the
signals.
Space Segment Control Segment User Segment
GPS

8. • User segment:
 This segment includes the
military and civilian users.
 This consists of a sensitive
receiver that helps to detect the
signals.
 This also comprises of a
computer to convert the data into
useful data.
 The GPS receiver is used to
locate the position
Control segment:
 This segment helps the entire
system to work efficiently.
 This takes care of the satellite
system ,updating the
transmission signals and
maintains the satellites in their
appropriate orbits.

9. WORKING PROCESS
GPS MODULE
 Connect GPS power supply with less than or
equal to 12 v dc power supply.
 Select mode selector switch towards RS 232
level.
 Initialize GPS with PC and allow for atleast
15 min.
 Record one cycle information with reference
to fixed command($GPRMC).

10. IDENTIFICATION OF GPRMC
Formatting starts with $ and ends with *
followed by two numbers.
SYNTAX:
$<SPACE>GPS
COMMAND<SPACE>PACKET ID
FLAG LONGITUDE FLAG LATTITUDE
FLAG REAL TIME DATE &END FLAGS.

11. FLAG
 If flag=A ,a valid packet is available.
 If flag=V ,repeat the procedure upto flag=A.
 Longitude-9 digit number, the first 4 can be considered
for implementation.
 Latitude-9 digit number, the first 4 can be considered
for implementation
Time format:
Time format needs adjustment with reference to
GMT.
Date format:
Date-month-year.

12. OPERATION:
Connect serial communication with system comm. port.
Take 12v dc input and apply to GPS.
Switch on GPS and select mode pin.

13. PIR SENSOR
 A Passive Infrared sensor.
 This measures infrared light
radiating from objects in its
field of view.
 Motion is detected when an
infrared source with one
temperature, such as a
human, passes in front of an
infrared source with another
temperature, such as a wall.

14.  The PIR Sensor senses the
motion of a human body by the
change in surrounding
ambient temperature when a
human body passes across.
 Then it turns on the lighting load
to which it is connected.
 The lighting load remains on until
it senses motion.
 Once the motion is seized it
switches off the lighting load.

15. GEOTAGGING THE MOVEMENT
 Initialize GPS.
 Initialize embedded board.
 Connect PIR sensor towards main module
and reset the system.
 Connect GPS receiver and reset the system.
 For movement observation allow object to
move less than 5m with 120 degrees
viewing angle with respect to PIR base.
 Notice movement along with GPS data and
identification of places.

16. 16X2 LCD:
 LCD (Liquid Crystal Display)
screen is an electronic display
module and find a wide range
of applications
 The 16X2 Parallel LCD is
an 16 bit parallel
interfaced LCD.
 This unit allows the user to
display text, numerical data
and characters

17. POWER SUPPLY
 230vAc mains are stepped down by
transformer.
 The transformer output is rectified by a
full-wave bridge rectifier.
 The capacitors used in the circuit bypass the
ripples present in the regulated power supply.

18. GPS AND PIR OVERVIEW
The GPS module is connected to the port3
The pir sensor is connected to the port2.
According to the interrupt priority the
microcontroller serves the external interrupt.
The serial interrupt is then served which is
produced by the GPS module.
 The location of that particular movement is
then displayed on the LCD.

19. ADVANTAGES
 Very easy installation.
 No separate wiring is required hence no
additional installation cost.
 PIR sensors are generally compact and can be
fitted into virtually any electronic device.
 They do not need an external power
source because they generate electricity as
they absorb infrared light.

20. LIMITATIONS
PIR sensors can only receive infrared light and
cannot emit it like other types of infrared
sensors.
 They can be expensive to purchase,
install, and calibrate as well.

21. APPLICATIONS
This project is widely applicable in
 Prohibited areas.
 Archeological surveys.
 Detection of unauthorized entries in the
border security.
 Navigation.
 Burglar alarm control panels.
 Home security systems.

22. FUTURE SCOPE
This project has it’s advancements in areas of
 Army
 Automobiles
 Aircraft
 Navy
 Archeological surveys

23. CONCLUSION
 The technology of the Global Positioning
System is allowing for huge changes in
society.
 More reliable and accurate measurements.
 Less costly to corporations - since the
error removing equipment will no longer be
needed.
 More affordable and accessible to
consumers.
 Greater incentive for the development of
new uses.
