This document outlines a project to detect alcohol in vehicles to prevent drunk driving. The system uses an ATmega32 microcontroller, alcohol sensor, LCD display, motor driver, buzzer, and GSM module. It analyzes breath for alcohol concentration and controls the vehicle if alcohol is detected by sending a signal via GSM. The hardware is powered by a 5V supply and software is programmed using Programmable Notepad and simulated in Proteus. The system aims to reduce road accidents by preventing drunk driving and notifying authorities if needed. Future work may include GPS and fingerprint identification to enhance location tracking and driver verification.

3. Why This Issue Important??
 Drunk Driving is major issue of our society.
 In year 2013, 1,10,839 people was die & 3,45,000 were
injured in road (by NHTSA).
 One person died in every 53 minutes.
 One in three people involved in alcohol related crashing.
 It’s affected not only you but your loved one’s also.
 Unawareness of the dangers of drunk driving in our
society.

Hardware require:

6. ATmega32:

7. Features:
 High-performance, Low-power.
 A Nonvolatile Program and Data Memories.
 Advance RISC Architecture .
 Real Time Counter with Separate Oscillator.
 Internal Calibrated RC Oscillator.
 32 Programmable I/O Lines.
 Power Consumption.
 Four PWM Channels.

8. Alcohol Sensor:

9. Alcohol Sensor:
 This alcohol sensor is suitable for detecting alcohol concentration
on your breath, just like your common breath analyzer.
 It has a high sensitivity and fast response time. Sensor provides an
analog output based on alcohol concentration.
 The sensor needs 5V power supply to operate.
• High sensitivity to alcohol and small sensitivity to Benzene.
• Fast response and High sensitivity.
• Simple drive circuit of 5V DC with analog output.
• Operation Temperature: -10 to 70 degrees C.

10. LCD:
 Liquid-crystal display televisions are television sets that
use LCD display technology to produce image.
 Liquid crystal displays consist of liquid crystals that are
activated by electric current

11. L293D Motor:

12. BUZZER CIRCUIT
•A buzzer or beeper is an audio
signalling device.
•Which may be mechanical,
piezoelectric, or electromechanical.
• Typical uses of buzzers include
alarm devices, timers and
confirmation of user input such as a
mouse click or keystroke

13. Gsm Module:

14. HARDWARE:

16. 3D View

17. drunk driving detection thus decrease accidents.
Quick analysis to presence of alcohol .
Small space covered in vehicle.
More suitable to other technique.
Control vehicle through Gsm.
Less cost & Less maintenance.
Protect the human & your loved one’s also.
It is not police dependent system.
Easy to install.
Advantages:

18. Disadvantages:
Highly sensitive to the atmosphere. Carbon monoxide, cigarette
smoke and many other environmental gases can effect the readings .
Other products such as some mouthwash or breath spray can
"fool" breath machines.

19. Application:
Alcohol Detector project” can be used in the various vehicles for
detecting whether the driver has consumed alcohol or not.
 This project can also be used in various companies or organization
to detect alcohol consumption of employees. .
This is used minimize the road accidents occurring due to drunk
driving which cause the loss of invaluable human life.
More than 7,000 road traffic deaths could be prevented every year
if alcohol detection devices were used in all vehicles

20. Software used:
• PROGRAMMABLE NOTEPAD(p n) used for
written the program.
• PROTEUS 7.7 SP2: Used for simulation by
loading the HEX file created in programmable
notepad(p n).
• Altium designer 10.0: it is used for pcb designing
and schematic layout.

21. Future Scope:
We can implement GPS technology to find out the location of the
vehicle.
We can integrated identity verification system which is finger
print based.
We can also integrated webcam system for identification of the
person.
