Arduino Breathalyzer Project using MQ3 alcohol sensor 096

Use Arduino to drive MQ3 alcohol sensor. Post Time: 2016-06-16 05:06:30 Category: Arduino Parts eBook. Objective: In this project, we will use Arduino to get alcohol concentration value from MA-3 sensor module and display the data to PC. When concentration is more than some Threshold , LED will flash.

Building a Breathalyzer with MQ-3 and Arduino - Daniel Andrade

Once we have R0, we can now use the information from the graph to calculate BAC. Using regression, I found the relationship between RS/R0 and mg/L to be:. I then use this formula to calculate the BAC in g/dL. This is the resulting Arduino sketch.
