This document describes an IoT and GSM based smart car parking system developed by four students and supervised by Sayeed Islam. The system uses sensors to detect vehicles and send data on available parking slots to a mobile app and users via SMS. It aims to reduce traffic congestion by allowing users to check parking availability remotely and book slots. The system was implemented using sensors, Raspberry Pi for data processing, a mobile app, and a motor. It provides real-time parking information and booking while allowing user authentication. The students tested various functions like single/multiple bookings and unauthorized access. The proposed low-cost system helps reduce traffic and supports smart cities alongside being cost-effective and real-time.

3. Due to growth of population a need of human becomes enlarge. The most
important need of people is vehicle therefore the number of vehicle on the
road side is increasing rapidly. Hence the traffic congestion occurs. So to find
out the parking space for their vehicle we develop an IoT and GSM based
smart car parking system. A mobile app is provided to the user to check the
parking slot is available or not and book a parking slot if slot is available or
not. This project will be implemented by placing some sensors on barrier
which would take signal of vehicle and give data if the slot is empty or not.
And using IOT it will send this result to user mobile app and using GSM
send SMS to user about slot empty or not.

4. Trends in Electronics Information & Communication Technology (RTEICT), May 1920,
2017, India. Work proposed in this system addresses the issue of parking in smart cities.
The system is implemented using low-cost IR sensors, Raspberry pi model 3b for real-time
data processing, E-parking mobile application, and Geared DC motor. The developed system
provides real-time information on the availability of parking slots in parking areas and allows
users to book parking slots from remote locations by using a mobile application and also
provides user authentication. The developed system is tested for different cases such as
single-user booking, multiple users booking, a user trying to book a reserved slot, and user
authentication. The proposed system is designed for 3 parking slots each having a single IR
sensor with an adjustable sensing range of up to 30cm. Proposed work not only reduces the
traffic congestion, but it is also providing authentication of the user, costeffective, real-time,
and helps in reducing carbon footprint.

10. NodeMCU ESP8266. NodeMCU is an open-source Lua
based firmware and development board specially targeted
for IoT based Applications. It includes firmware that runs
on the ESP8266 Wi-Fi SoC from Espressif Systems, and
hardware which is based on the ESP-12 module.
NodeMCU
IR Proximity Sensor
The IR transmitter continuously emits the IR light and
the IR receiver keeps on checking for the reflected
light. If the light gets reflected back by hitting any
object in front it, the IR receiver receives this light.
This way the object is detected in the case of the IR
sensor.

11. At the heart of the module is a SIM800L GSM cellular
chip from Simcom. The operating voltage of the chip
ranges from 3.4V to 4.4V, making it an ideal candidate for
direct LiPo battery supply. This makes it an excellent
choice for embedding in projects with limited space.
GSM Module
LCD Display
A 16x2 LCD means it can display 16
characters per line and there are 2 such lines.
In this LCD each character is displayed in 5x7
pixel matrix.

13. Working Process
First we programmed our microcontroller then connect all sensors,
display, GSM module. When proximity sensor got sensed by any
vehicle then it send a signal to microcontroller then it process the
signal as per program and show the result to display and mobile app
and send SMS to mobile using GSM.

14. Result
All the programming is done by the Arduino IDE and the program is
loaded in to the Arduino board. After interfacing of all components
according to the circuit diagram we get the desired output We have
successfully completed our project.

15. Advantages
 There is a greater sense of security due to the fact that patrons do not
actually walk to and from their own space.
 Mobile app based booking system.
 GSM Alert.
 There is high parking efficiency.
 There is no need for driving while looking for an available space.
Emissions are greatly brought down and reduced.
 The patrons wait for their car in a highly controlled environment.
There are less chances for vehicle vandalism.
 There is a minimal staff requirement if it is used by known.
15

16. Disadvantages
 There is a greater construction cost per space (but this may be offset by
the chance for lesser land costs per space and the system manufacturers
say that the operating and maintenance cost will be lower as compared to
a conventional ramped parking structure).
 Use of redundant systems will result in a greater cost.
 It may be a bit confusing for unfamiliar users.
 Internet speed.
 GSM Balance.

17.  We can use it to any Big Housing society’s parking to manage more
vehicles.
 We can use it to any Shopping Mall’s parking to manage more
vehicles.
 We can use it to any College, University’s parking to manage more
vehicles.
 We can use it to any Public parking place’s to manage more
vehicles.
 We can use it to any Industry’s parking to manage more vehicles.
 We can use it to any House’s parking to manage more vehicles..

18.  In future we add AI with this system.
 In future we add automatic billing system.
 In future we add double decker parking system.
Future Work

19. As the number of cars on the road continues to grow and the available
land space for infrastructure and development remains constant, there is
a greater need for solutions that can initiate faster and optimized parking
– minimizing the hassle and unnecessary congestion on the roads. This
is the ideal option for sustaining quick urbanization.
Discussion

20. The proposed system reduce drive frustration and traffic by providing
nearest parking area and available slot. As smart parking system increase
the service levels in operation, there is a lot of scope for innovations
and implementation through data standardization and management.
Basically smart car parking system save time, money, space and help to
simplify the often tedious task of parking.
