ABSTRACT Road accidents are very common in today’s busy life. Most of the people use private vehicles and sometimes being careless, people may drive in a drunken state.  This may lead to hazardous accidents.  To avoid such conditions, we have worked upon this project that enhances safety on roads. It aims to prevent drunk and driving and thus avoiding accidents 

INTRODUCTION An alcohol sensor is being used to detect presence of alcohol in the inner atmosphere of a car.  The sensor detection activates the system that is programmed in Arduino controller which will trigger an alarm and a flash light in order to keep driver in conscious state.  Engine will not start until alcohol sensor senses the absence of alcohol in inner atmosphere of a car. 

LITERATURE REVIEW World Health Organization’s , first ever Global Status Report on Road Safety reveals that 90% of deaths on the world's roads occur in low and middle- income countries (21.5 and 19.5 per lakh of population, respectively) though they have just 48% of all ed vehicles.  India has the second largest road network in the world with over 3 million km of roads of which 60% are paved. These roads make a vital contribution to the India's economy. According to a government report, road accidents in India killed 1,34,000 people in 2010 (an average of 336 a day). 

Accidents due to drunken driving are a major problem in India. The problem is unrecognized and hidden due to lack of good quality research data.  A study conducted by Alcohol & drug Information Centre (AIDC), India revealed that around 40% of the road accidents have occurred under the influence of alcohol. Young male drivers are at a high risk of such accidents.  Though some efforts are being taken to reduce the Road Accidents due to drunken driving, considering the gravity of the situation it is important to change strategies and mechanisms with foresight and effective implementation. 

BLOCK DIAGRAM

DESCRIPTION The functional block diagram of the Alcohol Detection With Vehicle Control system which is shown in the figure, mainly divided in to three main sections as follows.  Sensor output section: The MQ-3 alcohol sensor contains a kind of polymer which on heats changes its resistance according presence of alcohol in a car. It sends analog signals to the microcontroller in the form of several values according to intensity of alcohol.  The Microcontroller section: In this section the microcontroller AT-MEGA 328P receives the analog signal that comes from alcohol sensor via inbuilt Analog to Digital Convertor (ADC).  

The microcontroller processes the input data from sensor according to coding developed by the in ARDUINO software.   The Display & Controlling section: This section mainly consists of 16x2 LCD display and the mainly controlling action of the circuit. According to the alcohol detected in earlier section the microcontroller sets the condition as per program by . If alcohol is present in a car, then the microcontroller sends the message ” ALCOHOL DETECTED” & prints sensor value on the LCD display and it controls the car ignition system using relay driver which is connected to microcontroller and also sounds the pizeo Buzzer. It glows respective LED as per the state detected by the microcontroller.
