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.
Alcohol 3 click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
