How Does It Work?
The sensor IC used on Air Quality 4 Click is the SGP30 from Sensirion, a multi-pixel gas sensor for indoor applications. This sensor is a system of several metal-oxide sensing elements on a chip (pixels) used to measure and process readings of various gases in the air and output them as Total Volatile Organic Compounds (TVOC) [ppb] and CO2 equivalent signal [ppm].
The SGP30 sensors are made using advanced MOXSens Technology to provide unmatched robustness against siloxane contamination, ensuring long-term stability and accuracy. The sensor uses a dynamic baseline compensation algorithm and calibration parameters to provide accurate readings of TVOC and CO2eq properties.
Applications: A perfect solution for various air conditioning systems, ventilation systems, and other IoT applications where accurate, detailed, and reliable air quality readings are required.
