Smart Helmet for Accident Detection using GSM

Project Title

Smart Helmet for Accident Detection using GSM

Project Area of Specialization Computer ScienceProject Summary

Rate of accidents due to two wheelers is increasing day by day, the accident can be due to negligence of driver, lack of proper treatment on time there could be many reasons for lack of on time treatment but most important is the late arrival of ambulance or any other cause but in every case it can severely damage the victim even leads to the loss of life. So, we are proposing a solution in the form of “Smart Helmet” which is a type of protective headgear used by the rider and makes bike driving safer than before. The main purpose of this helmet is to provide safety for the rider. This can be implemented by using advanced features like alcohol detection, accident identification, location tracking, and sending immediate alert message to the home/ambulance by using multiple sensors, GSM module and GPRS.The first step is to identify whether the helmet is worn or not. If helmet is worn then ignition will start otherwise it remains off. For this, Force Sensing Sensor (FSR) sensor is used. The second step is alcohol detection. Alcohol sensor is used as breath analyses which detects the presence of alcohol in rider’s breath and if it exceeds permissible limit ignition cannot start. It will send message to the number saying that “Rider is drunk and is trying to ride the bike”. MQ-3 sensor is used for this purpose. The aim of this project is to make à protection system in a helmet for the safety of bike rider. The smart helmet that is made is fitted with different sensors responsible for detection. There are two main units in this project. Each unit uses a microcontroller. Signal transmission between the helmet unit and bike unit is done using a RF module. Force Sensing Resistor in is placed inside the helmet, where the actual human touch is sensed. It is determined by the helmet unit whether it is worn or not before starting the bike.MQ-3 gas sensor shown in Figure 2 is used for identifying the alcohol content from breath. It can be positioned just in front of the mouth.

Project Objectives

Our proposed system provides the facility of checking the presence of helmet. To identify whether the helmet is worn or not, for this we are using Force Sensing Resistor (FSR) sensor in the helmet.

To detect the amount of alcohol in the breath we are using MQ-3 sensor in the helmet near to the mouth of the rider.

To detect the location of the accident we are using GPRS and to send the message immediately to home or ambulance we are using GSM module.

Project Implementation Method

 we use accelerometer, which measures the static acceleration of gravity. Free-fall sensing unit senses if the bike is falling. And Bike unit take decision that accident is occurred or not. An RF transmitter module is a small PCB subject assembly capable of transmitting radio waves and modulating radio wave to carry data Transmitter modules are usually implemented alongside a microcontroller which will provide data to the module that can be transmitted. An RF receiver module receives the modulated RF signal and demodulates it. There are two modules, such as, super-heterodyne receiver and super-regenerative receiver. Super-regenerative modules are usually low cost and low power designs using a series of amplifiers to extract modulated data from a carrier wave. Digital vibration sensor (Figure 5, DFR0027) is a digital Plug and Play sensor block. It has vibration switch, digital input module and dedicated sensor expansion boards with the Arduino in combination. It can sense the weak vibration signals.

Benefits of the Project
