Description of the project:
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.

Description in detail:
This project is one of the important Sensor based project ideas. The main unit of this project is an “Alcohol sensor”. If the person inside car has consumed alcohol then it is alcohol detection is done 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.
Applications and Advantages:
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 analyzer 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.
Advantages of Alcohol Detector project:
1) “Alcohol Detection System in Cars” provides an automatic safety system for cars and other vehicles as well.
Future Development of the project:
1) We can implement GSM technology with alcohol detector. So Alcohol detection & vehicle controlling through text SMS will inform the relatives or owners of the vehicle about the alcohol consumption.
2) We can implement GPS technology so that once alcohol detection is done, the system will find out the location of the vehicle.
Question and answers about this project:
Question : Can we use GSM technology in this project?
Answer : Yes, we can implement GSM technology. If microcontroller detects presence of alcohol then it will send SMS to the owner of the Car or to the family members of the person driving the car.
Question : What are the drawbacks of this project?
Answer : If any person other than the driver has consumed alcohol and if system detects it then also it will not allow the car to start (even if the driver is not drunk)
Question : What is the functionality of comparator in alcohol detection project
Answer : Comparator has a potentiometer which gives a constant voltage at inverting terminal of comparator. Then at non-inverting terminal alcohol sensor output is given. It gives low pulse when alcohol level increases.
Question : Can you add a DC motor instead of Relay?
Answer : Yes, we can provide DC motor. Motor will be turned off if the alcohol is detected
Question : What is the use of LCD display in this project?
Answer : As this “Alcohol Detection System in Cars” is an educational project, we have to use LCD display to show various messages. This helps the students to view the current state, like Alcohol crossed harmful level. Motor started/ motor stopped. LCD also helps to find out the fault in the project as we can put various testing/break points in the program. In actual use we can remove LCD and replace it with various LEDs of different color to indicate status.
Question : In the project of alcohol detection with vehicle controlling (project code:1250) can we connect DC motor for working demonstration? How we want to connect and I also want step by step process of making this project?
Answer : We have already provided a DC motor with the “Drunk driver detection” project. Project report includes step by step process of how to make the project.
Question : Where the alcohol sensor is to be placed? Within the car or at the traffic control area? And what is the cost of alcohol sensor?
Answer : The alcohol sensor will be placed inside the car. It should be placed near the steering wheel so that it can sense the alcohol consumption of driver. Cost of alcohol sensor varies from Rs.300 to 800 depending upon the manufacturer.
Question : Is the alcohol sensing with engine locking also available using embedded system?
Answer : We have provided a DC motor to show demonstration of engine. DC motor starts when ignition key is inserted in lock. And DC motor stops when alcohol is sensed.
