Alcohol Gas Sensor Arduino

Detect the presence of alcohol with arduino.

Alcohol gas sensor arduino. Simply we have interfaced mq 135 gas sensor module with arduino and 16 2 lcd module for display. In this project we will go over how to build an alcohol sensor with an arduino. 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. Smoke detection using mq 2 gas sensor.

The alcohol gas sensor we used is the mq 135 sensor. How to use ky 037 sound detection sensor with arduino. You can measure changes in the intensity of sound in an environment. 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.

To design this arduino alcohol project circuit we have chosen the online eda tool called easyeda. 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 sensor has a long life and good sensitivity. Today we will build a breathalyzer using the mq3 gas sensor an oled display and arduino.

A breathalyzer is a generalized trademarked name for devices used for determining blood alcohol content from a breath sample. The alcohol sensor we will use is the mq 3 sensor. Circuit and pcb design using easyeda. Mq 3 alcohol sensor circuit built with an arduino.

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.
