Smart Helmet

Project Title

Smart Helmet

Project Area of Specialization Internet of ThingsProject Summary

The thought of developing this project came from our responsibility towards the society. As we can see many accidents occurring around us. Usually people die due to lack of treatment in proper time. The reasons for this may be many such as late arrival of ambulance, no person at place of accident to give information to the ambulance. We came up with this idea of giving the information about accident as soon as possible and in time. So we can minimize death rate in bike accident. We placed vibration sensors in different places of helmet where the probability of hitting is more which are connected to Arduino board. So when the rider crashes and the helmet hits the ground, the sensors sense and the Arduino extract GPS data using the GPS module that is interfaced with Arduino. When the data exceeds minimum stress limit then GSM module automatically sends message to ambulance or police or family members with GPS location. Helmet will have two buttons and can pick up or decline call through these  two buttons, we are going to design a mobile application  for helmet. Due to mobile app  we will able to find the exact location of a person.  And use the mini camera to captured the picture and vedios.There is one more reason for choosing this project is that we want to digitalize our society

Project Objectives

Aim of the project: The aim of project is to give information to the ambulance and family members about the accident as soon as possible so that they can take certain measures to save the life of the person who met with an accident. As we can see many accidents occurring around us. Usually people die due to lack of treatment in proper time. The reasons for this may be many such as late arrival of ambulance, no person at place of accident to give information to the ambulance. I came up with this idea of giving the information about accident as soon as possible and in time. So we can minimize death rate in bike accident. By mobile application we can also trace the location of a person wearing helmet. Mini camera to captured the picture and video of the memorable places.

Project Implementation Method

Methodology: The idea of this project is to give information about the accident to the ambulance and family members, so I have to chose GSM technology to give the information by sending SMS. We are using GSM module which has SIM card slot to place the SIM. Sending SMS alone can ?t help the driver, if we send and an SMS saying that accident had occurred where the ambulance will come without knowing the location of the accident.

We have included GPS and location will be sent to ambulance through SMS so they know the perfect information about  where and when the accident has occurred. For this we use GPS module to extract the location of the accident, the GPS data will contain the latitude and longitude values using which we can find the accurate position of the accident place. To run the GPS and GSM module we use  Arduino Mega 2560 is a microcontroller board based on the ATmega2560. The Arduino is a very user friendly device which can be easily interfaced with any sensors or modules and is very compact in size.

Arduino will send the SMS using the GSM module by keeping the GPS location in the SMS which is obtained from the GPS module. But when should all this be done? When accident occurs, how will the Arduino detect the accident? To solve this issues, we use a vibration sensor which is placed in the helmet. The vibration sensor is placed in the helmet such that it detects vibrations of the helmet. When the rider crashes, the helmet hits the ground and the vibration sensor detects the vibrations that are created when the helmet hits the ground and then the Arduino will send an SMS containing information about the accident and location of accident. This is the methodology used in the project.

Let me once again give a brief description about the working of project, when the rider crashes, the helmet hits the ground, the vibration sensor senses the vibrations and asks the Arduino to send SMS, the Arduino will send SMS through GSM module containing information that accident has occurred and the GPS location obtained from GPS module. 

Benefits of the Project

Significance of this work: This project is very useful in day to day life and adds extra safety while driving. Its like a virtual person at the place of accident which sends the information to the ambulance. This is not only useful in bike accidents only but also in car accidents, it can be implemented in car accidents by placing this device in the car and changing some threshold values of the vibration sensor. Use of this project makes your life secure at crucial times, especially when the accident occurs at a no man place, where there is no person to notice the accident. It helps in the situation where you can?t even move your body and in critical position. It automatically sends the information.

ARDUINO 2.1 Overview: The Arduino Uno is a microcontroller board based on the ATmega328 . It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, 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. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. Board has the following new features: ? 1.0 pinout : added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V.The second one is a not connected pin, that is reserved for future purposes. ? Atmega 16U2 replace the 8U2. ? "Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. 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 version 2.2 Schematic & Reference Design The Arduino reference design can use an Atmega8, 168, or 328, Current models use an ATmega328, but an Atmega8 is shown in the schematic for reference. The pin configuration is identical on all three processors.

Arduino will send the SMS using the GSM module by keeping the GPS location in the SMS which is obtained from the GPS module. But when should all this be done? When accident occurs, how will the Arduino detect the accident? I use a vibration sensor which is placed in the helmet. The vibration sensor is placed in the helmet such that it detects vibrations of the helmet. When the rider crashes, the helmet hits the ground and the vibration sensor detects the vibrations that are created when the helmet hits the ground and then the Arduino will send an SMS containing information about the accident and location of accident. This is the methodology used in the project.
