This is a simple code for detecting the alcohol content of the breath of a person using the alcohol sensor.This MQ3 sensor is used to detect the alcohol content in the air. Sensor Used : MQ3 alcoholmeter. Detection Gas : Alcohol gas Concentration : 0.04-4mg/l alcohol This is an alcohol sensor from futurlec,named MQ-3, which detects ethanol in the air. It is one of the straightforward gas sensors so it works almost the same way with other gas sensors. Typically, it is used as part of the breathalyzers or breath testers for the detection of ethanol in the human breath.
