Alcohol 3 click

MIKROE-3318 MiCS-5524

compact metal oxide sensor, 12-bit ADC, I2C, 3.3V

Alcohol 3 click is a gas sensor Click board™, 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. The MiCS-5524 sensor itself is a robust sensor, which can be used in harsh environment for gas leakage detection, in breath checking applications, early fire detection, etc.

Applications It can be used for various alcohol breath tester applications, early fire and gas leakage warning applications, VOC concentration warning applications, and similar
