Module with the MQ3 analog alcohol sensor. It allows you to detect gas and build a simple breathalyzer. The module is supplied with the voltage of 5 V and has an analog output (connector XH2.54) with a voltage proportional to the measured concentration. The sensor is characterized by high sensitivity of alcohol detection, regulated by a potentiometer.
