This work is on an alcohol sensing system that measures alcohol intake, displays percentage of alcohol and also sounds an alarm if it is above a particular threshold. Here we use an alcohol sensor circuit along with LCD display and a buzzer alarm. Our system first uses the alcohol sensor in order to detect alcohol. The sensor provides analog output. This analog output is now provided to the microcontroller for further processing. Based on the input the microcontroller calculates the percentage of alcohol and displays the same on an LCD display. It also sounds an alarm if the amount of alcohol exceeds a particular amount. Our system thus allows measuring amount of alcohol and then displaying percentage of alcohol measured. Also an alarm is sounded that indicates that measured alcohol is above a particular percentage.

CHAPTER ONE
1.0 INTRODUCTION
The Nigerian government has been advising its citizens not to drink and drive for decades, but for the first time, it may be able to physically stop you from getting behind the wheel while hammered.
The main purpose behind this project is “Drunk driving detection”. Now a days, many accidents are happening because of the alcohol consumption of the driver or the person who is driving the vehicle. Thus Drunk driving is a major reason of accidents in almost all countries all over the world. Alcohol Detector in Car project is designed for the safety of the people seating inside the car. Alcohol breath analyzer project should be fitted / installed inside the vehicle.
The main unit of this project is an “Alcohol sensor”. If the person inside car has consumed alcohol then it is detected by the sensor. Sensor gives this signal to a comparator IC. The output of comparator is connected to the microcontroller. Microcontroller is the heart of this project. It is the CPU of the complete circuit. Microcontroller gives high pulse to the buzzer circuit and the buzzer is turned on. At the same time a relay is turned off. Due to this the ignition of the car is deactivated.
1.2 OBJECTIVE OF THE PROJECT
The objective of this work is design a Drunken driving detection device, which detects the percentage of alcohol and displays the same on an LCD display. It also sounds an alarm if the amount of alcohol exceeds a particular amount.
1.3 PURPOSE OF THE PROJECT
The main purpose behind this project is “Drunk driving detection”. Thus Drunk driving is a major reason of accidents in almost all countries all over the world. Alcohol Detector in Car project is designed for the safety of the people seating inside the car.
1.4 APPLICATIONS OF THE PROJECT
Applications of Alcohol Detector in Car:
1) “Alcohol Detector project” can be used in the various vehicles for detecting whether the driver has consumed alcohol or not.
2) Breathing analyser project can also be used in various companies or organization to detect alcohol consumption of employees. Alcohol detection system in an automobile is a must feature which every cab or bus should have.
1.5 SIGNIFICANCE OF THE PROJECT
“Alcohol Detection System in Cars” provides an automatic safety system for cars and other vehicles as well.
The sensors can also aid an officer in the detection of alcohol during a stop, not to replace other more reliable and effective testing methods. This equipment helps provide law enforcement with tools to develop initial suspicion of someone breaking the law. Because they lack the precision of other tests and can detect alcohol from sources other than the suspected impaired driver.
1.7 FUTURE DEVELOPMENT OF THE PROJECT
1) We can implement GSM technology to inform the management of the factory about the alcohol consumption.
2) We can implement GPS technology to find out the location of the machine that is shutdown because of the drunk operator.
1.8 PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
Chapter one of this works is on the introduction to alcohol detector. In this chapter, the background, significance, objective limitation and problem of alcohol detector were discussed.
Chapter two is on literature review of alcohol detector. In this chapter, all the literature pertaining to this work was reviewed.
Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed.
Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
Chapter five is on conclusion, recommendation and references.
