Alcohol Sensor Arduino Project

The sensor detects the alcohol consumption by the smell of the breath.

Alcohol sensor arduino project.

In this project we will go over how to build an alcohol sensor with an arduino. 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. We know mq3 alcohol sensor is suitable for detecting alcohol concentration in air or from the breath this gas. 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.

This is a splash screen to introduce the project. 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. The project is built on arduino pro mini as the device is designed to be a handheld device. Project tutorial by scottc.

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. This is a sensor that is not only sensitive to alcohol particularly ethanol which is the type of alcohol which is found in wine beer and liquor. The alcohol sensor we will use is the mq 3 sensor. The heater pin on the alcohol sensor is then activated which can cause the program to hang.

The alcohol gas sensor we used is the mq 135 sensor. 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 ll learn how to use the ky 037 sound detection sensor with arduino. The project is built on arduino pro mini as the device is designed to be a handheld device.

Simply we have interfaced mq 135 gas sensor module with arduino and 16 2 lcd module for display. This arduino project will guide you how to make an automatic alcohol dispenser. In this project i am going to interface an alcohol sensor with arduino. You can measure changes in the intensity of sound in an environment.

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. How to use ky 037 sound detection sensor with arduino. The sensor detects the alcohol consumption by the smell of the breath.
