THROUGH ALCOHOL
DETECTION
1.INTRODUCTION
The current scenario shows that the most of the road incidents are occurring
due to drunk-driving.
The drivers who drink alcohol are not in an stable condition and so,rash
driving occurs on highway which can be risky to the lives of the people on
road,the driver inclusive.
The laws in India are currently prohibiting drivers to drink and drive so that
the fine can stop them to drink and drive.
Whatever, effective observation of inebriated drivers could be a challenge to
the policemen and road safety officers
this restricted ability of enforcement agents undermines each manual efforts
towards edge drink-drive.
Therefore need for an alcohol detection system that can function without
restriction of space and time.
MOTIVATION
These year the cases of traffic accident caused by drunk driving have
increased rapidly.
More and more people have realised that the drunk driving does great harm to
public security.
This time to develop a kind of system hasn’t been popularized, we tried to
develop this system.
This system won’t cost much, but it will bring much for it concentrates on
human’s safety.
this system has a preventative effect which can stop accidents from the
beginning.

3.PROBLEM STATEMENT
Drunken driving considered as one of the major reason of accidents in
wordwide.
Under the influence of alcohol shown as clear failure of perception
recognition and vehicle control.so by this accident occurs.
4.METHODOLOGY
The Alcohol Detection with Engine Locking system helps to reduce accidents
which are occurring due to drunk driving.
MQ-3 sensor detects the presence of alcohol in the surroundings. The sensor
provides output on the basis of the concentration of the alcohol, if the
alcohol concentration is higher the conductivity of MQ-3 sensor increases
which in turn gives the reading to ARDUINO.
If the reading is greater than the threshold level, ARDUINO will stop the DC
motor.
5.COMPONENTS…
1.ARDUINO UNO
The Arduino Uno is a microprocessor board built on the ATmega328P. It
contains a total of fourteen digital pins (6 of which are available as PWM
outputs), six analogue entrances, a crystal 16 MHz quartz flask, a reset
switch, an ICSP connector, and a charging connection It comes with everything
you'll need to get started with the microprocessor.
2.LCD
A liquid-crystal display (LCD) is a flat-panel display or other electronically
modulated optical device that uses the light-modulating properties of liquid
crystals combined with polarizers.
Liquid crystals do not emit light directly but instead use a backlight or
reflector to produce images in colour
3.ALCOHOL SENSOR
An Alcohol sensor detects the attentiveness of alcohol gas in the air. When a
drunk person breathes near the alcohol sensor it detects the ethanol in his
breath and provides an output based on alcohol concentration.
The MQ3 Alcohol sensor operates on 5V DC and consume approximately
800Mw.It can detect alcohol concentration ranging from 25 to 500ppm.
4.RELAY
The relay is a device that opens or closes the contacts to cause the operation
of the other electric control.
It detects the intolerable or undesirable condition with an assigned area and
gives the commands to the circuit breaker to disconnect the affected area.
Thus protects the system from damage
5.MOTOR
A DC motor is an electrical machine which converts electrical energy into
mechanical energy.
The basic working principle of the DC motor is that whenever a current carrying
conductor places in the magnetic field, it experiences a mechanical force.
Fleming's left-hand rule and its magnitude decide the direction of this force
6.RESULTS
If alcoholic person tries command on vehicle the alcoholic sensor determines
the existing of alcohol and shut down the vehicle engine and sound alarm by
which the nearby people will exchange the seat.
Peoples are aware of situation by the help of “LCD screen” present in the
vehicles and hence take required action.
We can avoided any kind of loss of life by using this system.
All equipments are totally tested and connected as required thereby giving
us the much needed result as shown in the image below
7.APPLICATIONS
The applications of this project are easily visible.
The Alcohol detection with engine locking system can be implemented in any
4- wheelers.
The Alcohol detection with engine locking system can help prevent accidents
due to drunk driving.
The Alcohol detection with engine locking system can be very helpful for
police.
The Alcohol detection with engine locking system prove automatic safety
system for cars and other vehicles.
8.FUTURE SCOPE
The future scope of this project is as follows
By using such technique the rate of road accidents can be prevented whose
main cause is drink and drive.
It can also prevent the vehicles from theft. It can be Integrated Drunk and
Drive Detection system detects solely the driver’s state. This could even be
extended by incorporating an extra alcohol odor sensor at the traveler seats
to discover the presence of alcohol within the air within the vehicle cabin.
Once alcohol is detected, the system problems each a voice alert and a
message alert on the navigation system monitor
