Simply we have interfaced mq 135 gas sensor module with arduino and 16 2 lcd module for display.
Alcohol sensor arduino code.
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.
Detect the presence of alcohol with arduino.
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.
The alcohol gas sensor we used is the mq 135 sensor.
In this project i am going to interface an alcohol sensor with arduino.
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.
And the led is an output will serves an indicator if the sensor has detected alcohol.
Paste this arduino code into the arduino ide and upload it to the arduino uno or compatible board.
Select file new.
If the grove lcd rgb backlight option is available in the examples folder then you are good to go.
In this tutorial we will learn how to detect smoke and inflammable gases using an mq 2 sensor.
The next block of code reads the sensor pin aout and stores the value in the integer value.
