Some of the applications that can be made by using this sensor are alcohol gas alarm portable alcohol detector gas alarms breathalyzer etc.

Alcohol gas sensor arduino.

This sensor has a long life and good sensitivity. A breathalyzer is a generalized trademarked name for devices used for determining blood alcohol content from a breath sample. Mq 3 alcohol sensor circuit built with an arduino. This is a sensor that is not only sensitive to alcohol particularly ethanol which is the type of alcohol that is found in wine beer and liquor.

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. You can measure changes in the intensity of sound in an environment. To design this arduino alcohol project circuit we have chosen the online eda tool called easyeda. In this project we will go over how to build an alcohol sensor with an arduino.

Hi guys welcome to this tutorial. We know mq3 alcohol sensor is suitable for detecting alcohol concentration in air or from the breath this gas sensor interfacing circuit can be used as breathalyzer. 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 alcohol gas sensor we used is the mq 135 sensor.

Circuit and pcb design using easyeda. The alcohol sensor we will use is the mq 3 sensor. You ll learn how to use the ky 037 sound detection sensor with arduino. Simply we have interfaced mq 135 gas sensor module with arduino and 16 2 lcd module for display.
