Abstract
This paper proposes smart monitoring of automobiles using IoT, which has the same functionality of conventional scanner-
automobile diagnostic device. It consists of a Raspberry pi, Arduino Uno board, Web page for the service centre and also various
sensors. The sensors attached in the car are connected with the Arduino board and the output is given to the raspberry pi and the
Ethernet field uploads these readings to the server. If any variation in the readings, the server will send SMS to the users mobile
to inform about the particular condition. And also it is possible to check the current status of the vehicle and there is special
facility called emergency request that is requested by the user to inform about the accident or sudden breakdown to the service
centre. It also has an obstacle sensor to sense any obstacles within a particular distance. Dust sensor fixed inside the car monitors
the dust content, which can cause health problems to passengers. If there occurs any such scenarios, an SMS will be sent to the
user. The vehicle will not get started if the seat belt is not worn by the driver. Detection of fire or water can result to automatic
unlocking of the seat belts.
Keywords: IoT (Internet of things)

I. INTRODUCTION
There are over 1,300,000 traffic accidents happening in the world every year. Casualties are mainly caused from malfunctioning
of automobile’s components and human negligence. This figure keeps rising and estimated to be increased exponentially in the
future. There is an urgent need from the automotive and logistic industry to have a low-cost but accurate fault diagnostic system
for running automobiles in order to minimize the rate of accident occurring on roads as well as minimizing economic losses.
Conventionally, the inspection of the health status of engines and their internal combustion processes are time consuming and
expensive[1]. It is because such inspection must be carried out by experienced mechanics and expensive equipment. In majority
cases, the mechanics will only recommend the automobile owners to renew the components long before their life time in order to
prevent accidents. However, this approach is definitely not economic. Lots of the components are thrown away even they only
have consumed half of their expected life time. Moreover, improper combustion process leads to waste of expensive fuel and
exhaustion of polluting gas. Hence, a low-cost but more comprehensive real-time engine diagnostic system is needed for
automobiles running on road[3] .And also if any urgent situation is occurred, it is very important to inform the service centre
about this. In this system there is a special feature called emergency request, which will inform the service centre about the
situation and they will detect the current vehicle position using GSM and will be able to provide their service.
Internet tends to be the backbone of all the technologies. The smart monitoring of automobiles using IoT is a progressive step
in the field of service centers. The proposed system can be used by any automobile user.
II. SYSTEM OVERVIEW
In the proposed system we have a Raspberry Pi, Arduino Uno board, Ethernet shield, and a web page. The sensors attached in the
cars connected to the arduino board and take the values from the sensors and the raspberry pi compares the values with the
threshold value and reports the changes to the server and also the user.
The server can view the current status of the car by viewing the webpage and the variation in the values will inform the user
by sending SMS to their mobile phones. The service dates are also sending as SMS to the user's mobile phone. There is a special
feature called emergency request used for inform the service centre about the problem of the car like breakdown or accident, the
Service centre workers can detect the current location of the vehicle and they will be able to provide the required services to the
particular user. The proposed system ensures the safety of the vehicle as well as the people inside the vehicle. Thus an accident
free journey is ensured, if you have the system installed in your vehicle

Because it has an ARMv7 processor, it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu
Core, as well as Microsoft Windows 10 (see the blog for more information).
The Raspberry Pi 2 Model B offers more flexibility for learners than the leaner (Pi 1) Model A+, which is more useful for
embedded projects and projects which require very low power.
Arduino, an open-source computer hardware and software company, project and user community that designs and
manufactures microcontroller-based kits for building digital devices and interactive objects that can sense and control objects in
the physical world. An Arduino's microcontroller is also pre-programmed with a boot loader that simplifies uploading of
programs to the on-chip flash memory, compared with other devices that typically need an external programmer. This makes
using an Arduino more straightforward by allowing the use of an ordinary computer as the programmer.
Fig. 4: Arduino Uno Board
The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which
6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header,
and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB
cable or power it with a AC-to-DC adapter or battery to get started. Currently, optiboot boot loader is the default boot loader
installed on Arduino UNO. It features the Atmega8U2 programmed as a USB-to-serial converter. The Uno is the latest in a
series of USB Arduino boards, and the reference model for the Arduino platform; for a comparison with previous versions.

There are various sensors used such as temperature sensor, pressure sensor, proximity sensor. We also monitor the battery
charge of the vehicle and also the engine. Along with all these, the water content in the radiator is also monitored.
IV. SOFTWARE SYSTEM
Raspbian Operating System:A.
Raspbian, a free operating system was based on Debian optimized for the Raspberry Pi hardware. Raspbian provides more than a
pure OS: it comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation on your

(J4R/ Volume 01 / Issue 01 / 016)
Raspberry Pi. Raspbian is still under active development with an emphasis on improving the stability and performance of as
many Debian packages as possible.
Features:B.
One of the main advantages of the proposed system is that there is no need of giving continuous attention to our vehicles. The
system takes care of the vehicle in a more efficient way by continuously monitoring the features of the vehicle like tyre pressure
,temperature, battery level, radiator content etc. Various sensors are used to detect the values and conditions of the vehicle
components. This sensor values are then passed to the arduino board which converts the analogue values into digital values. The
raspberry processor can only receive digital values. The sensors which we use in this system are analogue sensors. Therefore
there is a need to convert the analogue sensor values into digital. So we use the arduino microcontroller to receive the signals
from the sensors. The arduino receives the sensor values and then converts this values into digital.
The digital signals are then fed to the raspberry pi processor. The raspberry pi processor acts as a gateway which receives the
digital values from the arduino microcontroller. The values from the raspberry pi processor are passed to the server using a WiFi
adapter. The values from the sensors get uploaded into the database of the website and the values can be observed by the service
center authorities. If the received sensor values are more than the fixed threshold value, necessary action is performed by sending
an alert SMS to the user. The user will come to know about this and he can take necessary actions regarding this .Also if the
vehicle breaks down during travelling, the user can send emergency request to the service station by pressing a button in the
system which is connected to the vehicle. The GPS module attached to the system locates the position of the vehicle by finding
the latitude and longitude and sending the position to the server. In this system different sensors are used for detecting
temperature, dust, pressure, battery level and obstacle. The service station gets the latitude and longitude of the vehicle and sends
appropriate services to correct the problem. Also the website can view the details of all the registered users and also the sensor
values can be read directly from the web page. By this, the service center manager can keep track of the present condition of the
vehicle and take appropriate actions.
The service center manager keeps a calendar regarding the service dates of the vehicle. If the service date is getting near the
user gets notifications regarding the service date. The vehicle owner gets the service notification two days before the service
date. So in this way the user can service his vehicle at the correct time which avoids most of the problems. The main parameters
observed using the sensors include engine temperature, tyre pressure, battery level, oil content and water content in the radiators.
If any of the sensor values shows a value which is above the threshold value the service center can view this and take appropriate
actions. The proximity sensor senses any obstacles within a given distance. The fire and water detecting sensors detects the
presence of the same and these results in automatic unlocking of the seatbelts.
V. BENEFITS AND DRAWBACKS
Using this proposed system, the vehicles are easily maintained. The timely maintenance of the vehicles avoids the cascading of
vehicle parts. This system can be implemented with low cost. Since the alerts are sent as SMS, there is no requirement of smart
phones. The abnormality in the sensor values can help to detect the root cause of the problem. The service calendar reminds the
user of the service.
If there occurs any defect in the sensor, the it is difficult to locate it. So, in order to overcome the same, we can implement a
number of sensors and considering the average value of the sensors can be taken into account. Since the raspberry pi only takes
the digital values, an Arduino board is used to receive the analogue sensor values.
VI. RESULTS AND DISCUSSION
The service centre employee can view the current status of vehicle through the website in table format and he can do the
servicing in a better way, and he can see if there is any emergency request from his home page itself.

VII.CONCLUSION
We have a Raspberry Pi, Arduino Uno board , WiFi adapter and a web page. The sensors attached in the cars are connected to
the arduino board and it take the values from the sensors. This sensor values are compared with the threshold values in the
arduino board. These values are then fed to the raspberry pi processor. The changes are uploaded into the server. The user gets
necessary alerts regarding the increase in the values of the sensors. The server can view the current status of the car by viewing
the webpage and the variation in the values will be informed to the user by sending SMS to their mobile phones. There is no
necessity that the user should own a smartphone. As the proposed system uses SMS service for sending alerts to the customers, it
does not matter whether the user owns a smart phone. The service dates are also sent as SMS to the user's mobile phone. The
emergency request is used for informing the service centre about the problem of the car like breakdown or accident, The Service
centre workers can detect the current location of the vehicle and they will be able to provide the required services to the
particular user. The proximity sensor can avoid accidents to some extents. Also, automatic unlocking of seat belts when there
detects fire or water also adds to the safety measure. Dust sensor inside the car monitors the dust content and gives alerts to the
user as SMS. In other words, the vehicles are given the required care and attention which the owner can give. The vehicle gets
continuously monitored so all the problems can be avoided.
