This document presents a design for an automatic car parking system using a microcontroller. The system uses infrared sensors, a stepper motor, LCD display, and other hardware to detect vehicles and automatically guide them into available parking spaces. When a vehicle arrives, the IR sensors detect it and the microcontroller checks for empty spaces. If available, it opens the gate using the stepper motor and guides the vehicle in while updating the space availability on the LCD display. The system aims to make parking more efficient, reduce congestion, and provide real-time space information to users.

3. INTRODUCTION
➢ The proposed smart car parking
system will overcame all the
challenges & difficulties that are
there in conventional car parking
system.
➢ Smart car parking system will be a
revolutionary change in the city life ,
which is so filled with automobiles.

4. SCOPE
➢ Adopting of automatic smart parking system so that
availability of space could be known and enhanced security.
➢ Automatic car parking save time and fuel, reducing the
environmental pollution.

5. OBJECTIVES
➢ To develop an user friendly automated car parking system
which reduces the man power and time saving.
➢ To offer safe and secure parking slots with in limited area.
➢ To reduce traffic mess caused by an unplanned parking system.

6. HARDWARE REQUIREMENT
❑ Hardware requirement:
➢ Microcontroller (STC89C52)
➢ I R sensors
➢ Stepper motor
➢ LCD display
➢ Power supply

➢ Buzzer

7. MICROCONTROLLER
➢ The microcontroller used in the project is STC89C52.
➢ When it detects the car from the entry gate then it checks
whether there is any vacant space in the parking lot.

➢ And if it detects the car from the exit
gate then it decrement the count by
one.
Microcontroller (STC89C52.)
➢ If there is vacant space then it opens
the door and increases the overall
count in the parking lot by one.

8. INFRARED (IR) SENSOR
➢ Proximity sensor is used to detect
objects & obstacles in front of
sensor .
➢ Sensor keeps transmitting infrared
light & when any comes near , it is
detected by the sensor by
monitoring the reflected light from
the object. Fig.3 IR sensor

9. STEPPER MOTOR
➢ Stepper motor is used to open
and close the door. It is interfaced
with microcontroller and takes
command from the microcontroller
to rotate some particular specified
angle.

10. LCD DISPLAY
➢ LCD makes this instrument user interface friendly by displaying
everything on the display. It is an intelligent LCD module, as it has
inbuilt controller which convert the alphabet and digit into its ASCII
code and then display, this LCD will display the number of total
cars and available car and the time.

➢ The DS1302 Trickle Charge Timekeeping Chip contains a real
time clock/calendar and 31 bytes of static RAM. It communicates
with a microprocessor via a simple serial interface. The real time
clock/calendar provides seconds, minutes, hours, day, date, month,
and year information.

13. ALGORITHM

14. ADVANTAGES
➢ It ensures quick and automated parking & easy retrieval of
vehicles.
➢ Low cost system, providing maximum automation.
➢ Low maintenance levels are required by the system.
➢ Users can access that occupancy data to determine the
availability of slots.
14

15. APPLICATIONS
➢ The smart car parking system can be implemented in
• Offices
• Shopping malls and similar places.
➢ The user know the information of parking slot in advance.
➢ Friendly reorientation of cars for driving in and out .
15

16. RESULT EXPECTED
➢ When the vehicle comes near the parking slots the IR sensor
detects the vehicle and availability status of the slots is
displayed in LCD display further using the stepper motor ,
open and close of the gate of parking system is done.

17. CONCLUSION
The system can be used at all places starting from domestic to the
industrial sectors. The simplicity in the usage of circuit helps it to
be used by a large number of people, because people with less
knowledge of hardware can also use it without facing any problem.
This Automated car parking system enables the parking of vehicles
and thus reduces the time taken to check the space to be used by
displaying the spot where the space for parking is available on an
LCD display by using IR sensors at the entrance
