This is a beginner project that can be done in two hours if you have the specified materials and if you follow this useful tutorial.
The creator used one of our products – the essential Alcohol Click, which has high sensitivity to alcohol and it can be used to detect alcohol in concentrations from 0.04 to 4mg/l. It was designed to run on a 5V power supply only, and it communicates with the target microcontroller through the AN pin on the mikroBUS™ line. The Alcohol Click is ideally used for a portable alcohol detector and a breathalyzer for estimating BAC (blood alcohol content).
With this demo, you will create a device capable of estimating blood alcohol content from a breath sample, thus making your own alcohol sensor.
