DESCRIPTIONThe 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.

MICROCONTROLLER

The microcontroller used is AT89C52.

This is an 8 bit microcontroller.

It has a 8k of reprogrammable flash memory.

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.

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.

G P S

• 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.

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).

 

IDENTIFICATION OF GPRMC

Formatting starts with $ and ends with * followed by two numbers.

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 implementationTime format:

Time format needs adjustment with reference to GMT.Date format:

Date-month-year.

OPERATION:

Connect serial communication with system comm. port.

Take 12v dc input and apply to GPS.

Switch on GPS and select mode pin.

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.

 

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.

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.

 

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

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.

GPS AND PIR OVERVIEW

The GPS module is connected to the port3The 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.

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.

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.

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.

FUTURE SCOPE

This project has it’s advancements in areas of

Army Automobiles Aircraft Navy Archeological surveys

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.
