SMART HELMET FOR ACCIDENT PREVENTION

Abstract

An accident is a specific, unexpected, unusual and unintended external action which occurs in a particular time and place, with no apparent and deliberate cause but with marked effects. Carelessness of the driver is the major factor of such accidents. Smart Helmet for Motorcyclist is a project undertaken to increase the rate of road safety among motorcyclists. This project is developed for the purpose of bike rider safety using smart helmet. The helmet consists of alcohol sensor and RF module. As soon as owner wears his helmet, alcohol sensor evaluates the breath of the user. The alcohol sensor is used to detect whether the person has consumed alcohol or not. This sensor information is sent to the controller and it analyses these signals and generates the control signal. This control signal is transmitted to the RF receiver through RF transmitter. RF receiver receives the signal from RF transmitter and sends signal to the microcontroller. It analyses the signal and if the corresponding signal get received, it operates the engine through driver section. The engine should not turn ON, if any these conditions are violated. And the button is placed on the helmet to start the engine of the vehicle. If the user neither cannot press the button nor drinking alcohol, the smart device cannot operate the vehicle.
