Air quality 4 click is an advanced air quality sensing device that combines multiple metal-oxide sensing elements on a chip to provide detailed information of the air quality parameters. This click can output a TVOC value readings as well as the CO2 equivalent concentration readings in an indoor environment. Besides these compensated attributes, the click can also output raw values of H2 and Ethanol in the air, that can be used to calculate gas concentrations, relative to a reference concentration.

The sensor used on Air quality 4 click is actually a complete system of sensors on a chip, featuring I2C interface, a temperature controlled micro hotplate, and two compensated and processed indoor air quality signals. It is produced using the proprietary CMOSens® technology, which provides very detailed information and robustness against air contamination. These attributes make Air quality 4 click a perfect solution for various air conditioning systems, ventilation systems and other IoT applications where accurate, detailed and reliable air quality readings are required.
