Alcohol Sensor Arduino Project

The heater pin on the alcohol sensor is then activated which can cause the program to hang.

Alcohol sensor arduino project.

The alcohol sensor we will use is the mq 3 sensor. The sensor detects the alcohol consumption by the smell of the breath. When the arduino is powered up you will be presented with a message alcohol project by arduinobasics. 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 alcohol gas sensor we used is the mq 135 sensor. In this project i am going to interface an alcohol sensor with arduino. Interfacing gas sensors with arduino board is simple task and you just need to put correct code to arduino microcontroller through ide. Project tutorial by scottc.

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. 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. 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 project is built on arduino pro mini as the device is designed to be a handheld device. 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 sensor detects the alcohol consumption by the smell of the breath. 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.

This arduino project will guide you how to make an automatic alcohol dispenser. We know mq3 alcohol sensor is suitable for detecting alcohol concentration in air or from the breath this gas. You can measure changes in the intensity of sound in an environment. This is a splash screen to introduce the project.

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 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.
