Abstract – In this project, the design and implementation of
portrayed over, the sensor isn't delicate, during a demo, the sensor should be presented to the liquor fume.
an Alcohol Detection with Engine Locking for cars using the Ultrasonic Sensor and Arduino-UNO as the controlling unit is done. The system will continuously monitor the level of alcohol concentration by alcohol detection sensor and thus turn off the engine of the vehicle if the alcohol concentration is above the threshold level. This model will also send a message to the registered mobile number with the location of the vehicle using the SIM900A.
For this purpose, pour little alcohol (brandy or whiskey) into a small cup and place the sensor a little above the cup with a gap of 2 to 3 cms approximately. Contingent upon the liquor fume focus in the air, the conductivity of the sensor will be changed and in light of this conductivity, outplaced in the structure of voltage levels will be varied automatically. These varieties are observed through the operation amp and a high sign will be created at whatever point the sensor recognizes liquor fumes in the air.
Key Words: Arduino UNO, Ultrasonic sensor, Buzzer, LED, SIM900A, MQ-3 Sensor, DC Motor.
1. INTRODUCTION
The result of the MQ-6 sensor is utilized to set off the Op-amp, this operation amp arranged as a voltage comparator can produce a rationale high sign when sensor yield is greater than the reference voltage. Based on this signal, the microcontroller used as the processing unit is programmed to energize the alarm and flashing type red light simultaneously. In addition to the simulated ignition in the form of push-button and though it is activated, the motor will not be energized, creating the situation of engine shutdown. The innovation introduced here is exceptionally basic, it tends to be utilized as a demo module, yet when it will be utilized for genuine applications, every one of the vehicles should be furnished with genuine sensors which can recognize even a little grouping of liquor fumes present in the air.
The concept described in this project report is aimed to regret the drunken driver by not allowing driving the vehicle. When this system is installed in a vehicle over the dashboard and detects the drunken driver through the alcohol sensor, the simulated vehicle presented here with a DC motor, which will be stopped automatically, treated as engine shutdown. Since the availability of the exact sensor is not possible and since it is a prototype module, the basic concept is proven with the universal sensor which can detect all sorts of toxic gases, petroleum products, smoke, etc, in addition, To the alcoholic vapor. The sensor used here is named MQ6. Since it can detect all sorts of toxic vapor and is available easily everywhere, it is said to be the universal sensor. This sensor is used here to detect alcoholic vapors. Presently, this kind of sensor can be used for goods transport vehicles, because these vehicles will not carry passengers. At the point when this sensor is utilized in vehicles, it is hard to recognize the tanked individual in light of the tipsy travelers. Henceforth it is prescribed to involve this innovation in trucks just because the truck contains a separate lodge for the driver and his associate. If a proper sensor is used, it can be installed in cars also. One benefit of utilizing this sensor is that it cannot distinguish minimal far fumes, since it isn't the case delicate. It is supposed to be an advantage since it shouldn't identify other tipsy people the individuals who are minimum away from the driving wheel. This shows that the sensor should be introduced over the dashboard and that direction should be extremely close toward the driving wheel. Assuming that this sort of course of action is made in the lodge, the framework can identify just a tipsy driver. As

LITERATURE SURVEY
These days, many accidents are happening because of the alcohol consumption of the driver or the person who is driving the vehicle. Alcohol Detectors installed inside the vehicle can provide safety to the people seating inside the car. An alcohol breath analyzer should be fitted/installed inside the vehicle. Another age of innovation is coming to fruition around frameworks that keep vehicles from working assuming the driver is tanked. Scientists say the innovation is promising to the point that they contrast it with the coming of the safety belt concerning its true capacity. This is the best option to prevent drunken driving.
