The Alcohol Detection System with Buzzer Indication project is a sensor-based project in which we have used an Alcohol sensor for the detection of alcohol. If the alcohol percentage crosses the threshold value then the buzzer will be turned on. We have used an Analog to digital converter IC in this project so that the alcohol percentage can be shown on an LCD display. We have used LCD for Displaying project titles and other messages. It also shows the alcohol percentage and if the alcohol percentage crosses a certain level then it shows an alert message on the LCD.
In this project, an alcohol sensor senses the alcohol. In this project, we have used a microcontroller from an 8051 family and the microcontroller is 89s51. We have used ADC IC because the sensor gives an analog value. This project is very useful in areas where alcohol consumption is banned like in colleges, institutes, hospitals, and temples.
Applications of Alcohol Detection System with Buzzer Indication
We can use alcohol detector projects in schools, colleges, and university campuses to detect whether students have consumed alcohol or not.
This can be used in temples.
The alcohol detector system project can be used in a voting booth at the time of elections.
We can use this project in Hospitals.
Different industries or companies.
Advantages of Alcohol detector
This alcohol detector project is easy to use.
This project is very cost-effective.
Future enhancements of the project
We can add a GSM modem to this project and then we can send SMS alerts from this project.
