Alcohol Sensor Arduino Project

In this project we will go over how to build an alcohol sensor with an arduino.

Alcohol sensor arduino project.

Interfacing gas sensors with arduino board is simple task and you just need to put correct code to arduino microcontroller through ide. The alcohol sensor we will use is the mq 3 sensor. This is a splash screen to introduce the project. When the arduino is powered up you will be presented with a message alcohol project by arduinobasics.

Mq 3 alcohol sensor circuit built with an 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. 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. Project tutorial by scottc.

The project is built on arduino pro mini as the device is designed to be a handheld device. 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. How to use ky 037 sound detection sensor with arduino.

We know mq3 alcohol sensor is suitable for detecting alcohol concentration in air or from the breath this gas. 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. The sensor detects the alcohol consumption by the smell of the breath. 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 project is built on arduino pro mini as the device is designed to be a handheld device. 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. You ll learn how to use the ky 037 sound detection sensor with arduino. This arduino project will guide you how to make an automatic alcohol dispenser.

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. 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.
