Product Code: MIKROE-3318

The Alcohol 3 Click Board? is a gas sensor, equipped with the MiCS-5524, a compact metal oxide (MOS) sensor. This sensor reacts to the presence of deoxidizing and reducing gases, such as ethanol (also known as alcohol). Its impedance changes as a result of a catalytic reaction, allowing it to be used in a voltage divider configuration. This voltage can be sampled by an accurate A/D converter (ADC), allowing data to be read directly over the I2C interface.
