Volatile Organic Components Sensor
This is an MiCS-5524 sensor mounted on an adapter board that makes it compatible with TO39 sockets that were designed for the obsolete MiCS-5521. If you have hardware that uses an MiCS-5521 and you need to replace the sensor, this module can be a drop-in replacement as the specs of the two sensors are nearly identical. It's also good if you just want a VOC sensor that's easy to work with for prototyping.
The MiCS-5524 is a resistive sensor that responds to a great variety of gases, such as Carbon Monoxide (CO), Hydrocarbons and Volatile Organic Compounds. Its resistance varies between 1000kΩ and 2kΩ approximately. This sensor is powered through a 2.5V voltage regulator, with consumption of approximately 32mA.
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.
