Mikroe AIR QUALITY 4 CLICK

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 clicks a perfect solution for various air conditioning systems, ventilation systems and other IoT applications where accurate, detailed, and reliable air quality readings are required.

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 actually a system of several metal-oxide sensing elements on a chip (pixels), used to measure and process readings of various gasses in the air and output them in a form of two complementary air quality readings – Total Volatile Organic Compounds (TVOC) [ppb] and CO2 equivalent signal [ppm].

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.
