Alcohol Sensor Arduino Code

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.

Alcohol sensor arduino code.

Make sure the alcohol sensor is not connected to the arduino while uploading your code to the. Paste this arduino code into the arduino ide and upload it to the arduino uno or compatible board. 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. 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. The alcohol gas sensor we used is the mq 135 sensor. This is because the sensor is an input to the arduino for the arduino to read and process the sensor value. In this project i am going to interface an alcohol sensor with arduino.

And the led is an output will serves an indicator if the sensor has detected alcohol. 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. 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. If the grove lcd rgb backlight option is available in the examples folder then you are good to go.
