Mostofa Hossain, Associate Professor and Head of the Department of Mechanical Engineering, Sonargaon University (SU), for giving these opportunities and permission to do this project. This paper deals with the design and development of an IoT-based embedded system for detecting the vehicle health condition and safety by monitoring various parameters of a vehicle based on some threshold value. This helps to increase the lifespan of the vehicle as well as the engine.
It also helps in preventing sudden disruptions in vehicle operation that can lead to any kind of accident. Many people occasionally visit the service center for vehicle servicing and maintenance, but many people do not worry about this issue due to many limitations, it may be lack of time or overload, etc. If the manufacturing company (service provider) can monitor the health of the vehicle remotely, it would be a useful service for both the vehicle owners and the company concerned.
According to relationship, we have developed a system with IoT based where hardware part consists of microprocessor responsible for collecting and processing data based on various parameters of the vehicle with the help of sensors and send to the server over a unique IP -address while the software part consisting of a web application is responsible for receiving the data and stores it in the database that can be retrieved later to create reports of the vehicle for any kind of requirements. This project aims to develop an embedded system for vehicle health detection by monitoring the internal parameters used to evaluate the vehicle's current state of health. A real-time evaluation system is defined that can be used for rapid condition screening and provide reliable information about the vehicle conditions.
The OBD-II system allows monitoring of most electrical systems on the vehicle.
LITERATURE REVIEW
Background
Literature survey
12 | P a g e relevant parameters to determine whether the vehicle to be diagnosed is running out of order or normal operation. The disadvantage of this approach is that the available bandwidth is limited; it is not possible or efficient to transmit performance parameters to the fleet database. It continuously monitors the flow of data generated by a moving vehicle using an on-board computing device, identifies emerging patterns, and reports these patterns to the central control server using a low-speed wireless network connection if necessary.
Focus on Study
- VEDAS
- MINE FLEET
When a matrix is found with a change in the spectral distribution, Principle Component Analysis is made for the matrix. The article assumes that when the vehicle is certified as good health, the behavior of the vehicle can be observed and the cluster becomes stable. If the observed data point falls outside the stable cluster, the vehicle is in poor health.
Although the Principal Component Analysis is done only when there is a spectral disturbance, the Covariance matrix is done over a fixed interval [5]. Only for the correlation coefficient subset of the data is found in the large sparse matrix. Further, when the car undergoes maintenance it is periodic and based on the mileage of the car.
Analyzes generated from the vehicle are sent to a server over the wireless network at predetermined intervals. The extensive analysis of data will be done in the control base and further on the web server.
Load Sensor
Compared to VEDAS, the mining fleet is more suitable for continuous low overhead monitoring. Past collected crash data from SAWUR (Situation Awareness with Ubiquitous Data Mining for Road Safety) database is used in this paper to arrive at the prediction model to minimize the risk of an unexpected failure. It used the same technology as the mining fleet, but improved it by using social networks.
Same as the mining fleet, the onboard module is equipped with embedded devices, PDA to perform data stream mining. The voltage meter is one of the most important sensors of the electrical measurement technique that is applied to the measurement of mechanical quantities.

In fact, you already are; the Arduino language is simply a set of C/C++ functions that can be called from your code. Power LED Indicator – This LED illuminates whenever the board is connected to a power source. Ground Pins – There are several ground pins on the Arduino and they all work the same.
Analog pins – These pins can read the signal from an analog sensor and convert it to digital.
Programing on Arduino
Menu bar: Provides access to the tools needed to create and save Arduino sketches. Upload Button: Sends the code to the connected board, such as the Arduino Uno in this case. Sketch Name: When the sketch is saved, the name of the sketch is displayed here.
Serial Display: When the board is connected, this will display the serial information about the Arduino. Code Area: This area is where the code for the sketch has been compiled that tells the board what to do. Text console: Displays the details of an error message, the size of the compiled program, and additional information.
Card and Serial Port: Tells which card is being used and which serial port it is connected to.
Arduino Nano is better than Arduino Uno

In integrated circuit design automation, the term "circuit design" often refers to the step of the design cycle that produces the integrated circuit schematics. Input devices are load sensor, fuel level indicator sensor, brake shoe/brake pad worn indicator sensor, vibration sensor and GPS etc. To achieve the design and fabrication of IoT based vehicle health monitoring concepts and safety techniques, a scope with fabricated load sensor, fuel level indicator is needed indicator sensor, brake shoe/brake pad worn indicator sensor, vibration sensor, LCD screen, buzzer, GPS and connecting wire etc.
According to the voltage division rule, get here an analog voltage measured by Arduino Nano. According to the analog voltage, Arduino nano provides the required digital signal to display on LCD monitor by as junk unit as well as to notify through mobile applications and when the fuel level exceeds a specific level (below 20 junk), then the buzzer sounds the alarm for filling the fuel. According to the input signal, Arduino nano supplies the required voltage to the buzzer for warning, displays the data on an LCD monitor as well as notifies through mobile applications where the buzzer works as an actuator.
According to the data, the Arduino makes an output signal on the screen as a percentage through the LCD monitor, as well as notifies through mobile applications. If the brake shoe/pad wear exceeds the indicated level (below 20%), the Arduino sends a signal to the buzzer to beep so that the driver is aware. In this project, we have developed a system that stands to notify the owner of the accident or the result of the vehicle crash.
When the vehicle might fall in any accident, the microcontroller immediately receives the fall signal according to the vehicles vibration. In this project, LCD screen is used to display current records such as fuel in waste, brake shoe/pad wear indication, load status and accident status of the vehicles. GPS or Global Positioning System is a satellite navigation system that provides location and time information to the user in all weather conditions.

Plug one end of the USB cable into the Arduino Uno and then the other end of the USB into the computer's USB port. The AIA file is also used to export and import projects to and from a computer for the web application.
