Alcohol Sensor Arduino Project

In this project i am going to interface an alcohol sensor with arduino.

Alcohol sensor arduino project.

Mq 3 alcohol sensor circuit built with an arduino. Interfacing gas sensors with arduino board is simple task and you just need to put correct code to arduino microcontroller through ide. This is a splash screen to introduce the project. In this project we have designed alcohol level meter using arduino mq 135 alcohol gas sensor for measuring the level of alcohol in humans breathe.

You can measure changes in the intensity of sound in an environment. The project is built on arduino pro mini as the device is designed to be a handheld device. Here i have designed an arduino shield pcb using easyeda online pcb simulator and designer arduino alcohol detector will detect the alcohol level in breath and by using some calculations in code we can calculate the alcohol level in breath or blood and can trigger some alarm. The sensor is an analog as well as a digital sensor which on its analog pin outputs the analog voltage proportional to the alcohol level.

Simply we have interfaced mq 135 gas sensor module with arduino and 16 2 lcd module for display. The heater pin on the alcohol sensor is then activated which can cause the program to hang. The sensor detects the alcohol consumption by the smell of the breath. This arduino project will guide you how to make an automatic alcohol dispenser.

The project is built on arduino pro mini as the device is designed to be a handheld device. We know mq3 alcohol sensor is suitable for detecting alcohol concentration in air or from the breath this gas. Here simple arduino alcohol sensor code is written to interface mq 3 gas sensor alcohol with arduino board in this case we used arduino uno board. The sensor is an analog as well as a digital sensor which on its analog pin outputs the analog voltage proportional to the alcohol level.

Project tutorial by scottc. The alcohol sensor we will use is the mq 3 sensor. In this project we will go over how to build an alcohol sensor with an arduino. How to use ky 037 sound detection sensor with arduino.

User no need touch anything to get alcohol just come near ultrasonic sensor alcohol will be pushed out then an audio file will be played to inform to user should keep hand to be cleaned meanwhile the oled screen will display thank you. When the arduino is powered up you will be presented with a message alcohol project by arduinobasics. You ll learn how to use the ky 037 sound detection sensor with arduino.
