ABSTRACT: Alcohol driving is the leading cause of road accidents. Alcohol Detection will stop the vehicles and
it manually scan the drivers breadth analyzers. In this system it allows a alcohol sensor with arduino board along with a buzzer to give alarm that alcohol is detected and it automatically lock the vehicle motor. Then the system first allows configuring the user’s numbers into the program. And the driver is drunk by alcohol above permissible limit sensed the input triggers by providing required voltage. Thus the system provides alcohol detection using engine locking through arduino incidents automatically.
Keywords: Arduino, Buzzer, Engine locking, Sensor, Vehicle.


One major reason of deaths on Indian roads is accidents due to drunken driving. This happens because of drunken people being able to take control of vehicle even after being drunk. In our project, we propose to solve this problem by designing a system which automatically switches off the vehicle’s engine whenever alcohol of certain quantity is detected in the driver’s breath. As soon as the presence of alcohol is detected, the micro-controller stops the engine of the vehicle and a siren is blown to alert nearby people to convey that something is wrong with the vehicle, so that nearby people can interpret gravity of the situation and inform the concerned authorities to avoid any kind of incident. This system when implemented in vehicles will not only avoid the deaths and property loss due to drunken driving, but will also help in reducing the total number of accidents which occur due to this. Moreover, people in other vehicles or pedestrians will be much more safe because of the vehicle being stopped right away.


The author has proposed a method to detect alcohol but uses GPS and GSM module which increases the overall cost which could be avoided. In our project, we are using a siren which will be more cost efficient. Use of siren will alert the people nearby and hence any kind of necessary action can be taken. The authors propose to use a smart helmet to avoid accidents. There are many faults with their design. A major shortcoming is the limitation ofits application to only vehicles which use helmets,i.e 2 wheeler's which is not a probable idea while driving, especially for short distances. Another drawback being, the system when implemented makes the helmet too heavy which is not

favorable for driving. Also, they have used an expensive micro controller whereas we are using open source hardware, which is very cheap. The authors discuss about complex health monitoring systems and infrared sensor to detect the presence of alcohol. A major drawback of this system is the possibility of a false alarm. The system is designed in a manner that even a slight change in some particular condition can result in ringing false alarms even though everything was normal. In our project, we are using only the required technology thereby making the system more reliable and cost effective when implemented.
The authors have proposed a system to prevent the accidents due to drunken driving. Major drawback of this system is that they have used PIC16F877A micro controller which is not as useful as Arduino Uno micro controller that we are using. Also they have used an old design system which is not useful and increases the overall cost of the system which makes it expensive and somewhat unaffordable to certain segments of society thereby limiting its scope to be used. Hence, our system is more cost effective and can be easily afforded. The authors discuss the problem of drunken driving and propose to solve it by suggesting a system. However, the major drawback of their system is that they are using MQ2 alcohol sensor which is not accurate and is not specifically sensitive to alcohol. In our project, we are using a MQ3 sensor which is designed to be accurate towards alcohol detection which gives more accurate results. The author has tried to design a system to tackle the problem of helmet negligence and alcohol detection at the same time. The system is overly complex. Also, this system has a limited scope usage because it can work only with 2 wheeler's and not with any other segment of vehicle. However, our system can be integrated to not only 2 wheeler's, but also with any kind of vehicle thereby preventing more accidents and saving more people.
In this proposed system uses MQ3 alcohol sensor with arduino along with buzzer which makes a sound to identify the alcohol is detected or not and DC motor which is to besensed by the alcohol and it automatically stops the motor. And the system check the permissible limit then the sensor will be triggered the processor about the respective voltage. Thus the system will automatically stop the motor and it gives a siren to the users.

An alcohol sensor recognizes the mindfulness of liquor gas noticeable all around and analog voltage is an output reading. The sensor can activate at temperatures going from - 10 to 50° C with a power supply is under 150mA to 5V. The detecting range is from 0.04 mg/L to 4 mg/L, which is appropriate for breath analyzer.
The MQ-03 alcohol sensor comprises of a tin dioxide (SnO2), a point of view layer inside aluminium oxide smaller scale tubes (measuring cathodes) and a warming component inside a tubular packaging. The end face of the sensor is encased by a stainless steel net and the posterior holds the association terminal.When alcohol detected by this sensor, the micro controller sends required voltage to the buzzer, so that it sounds continuously. Ignition on and off condition monitored by the micro controller through relay switch.
A program for Arduino hardware may be written in any programming language with compilers that produce binary machine code for the target processor. Atmel provides a development environment for their 8-bit AVR and 32-bit ARM Cortex-M based microcontrollers: AVR Studio (older) and Atmel Studio (newer).
● Operating system: Windows, macOS, Linux ● Developer(s): Arduino Software ● Platform: IA-32, x86-64, ARM Arduino 1.8.0: The Arduino integrated development environment (IDE) then it is the a cross-platform application (for Windows, macOS, Linux) that is written in the programming language Java. It is used to write and upload programs to Arduino.
Finally after the design of system the input is identified by the sensor through the breathe of a human. In the next scenario the levels of alcohol is measured by the sensor and compared with the set-in limits. If the set limit of consumption in alcohol is less than the alcohol consumed by the person the system of activating relay is initiated which in turn activities the automatic lock on the vehicle i.e, stops the motor if it is in running state or it is unable to start. We can also give a comparative report of study with the variables of considering the internal factors. RTOS is the part where the comparison is needed in terms of time taken to account with respect to the interrupt latency and response time. Interrupt latency is the time taken to respond for the interrupt and the response time is the least amount of time taken to respond for the input given.

In this project we have developed a real time model that can automatically lock the engine when a drunken driver tries to drive a car. This is a developed design to efficiently check drunken driving. In this system a realistic social technique has been proposed to eliminate the loss caused due to drunken drivers. It has also been assured in a more technical way, so as to appreciate the use of RTOS which also gave the importance in the occurrence of interrupts as well as its execution. This could also be extended to the heavy vehicles, air bus, navigating vehicles, sense detection machines. These are also extended to bio medical fields, software development industries.
