The MiCS-5524 is a sensor whose resistance varies in the presence of small concentrations of a variety of gases, such as Carbon Monoxide (CO), Hydrocarbons and Volatile Organic Compounds (VOCs). This value varies between 2kΩ and 2MΩ approximately, providing high accuracy throughout the output range. The sensor's resistance in air, as well as its sensitivity, can vary between different units, so it is recommended to calibrate the sensor before including it in your application.
