Overview
Air Quality 3 Click_ is the air quality measurement device, which is able to output both
equivalent CO2 levels and total volatile organic compounds (TVOC) concentration in the indoor
environment.
The Click board™ is equipped with the CCS811 state-of-the-art air quality sensor IC from ScioSense, which has an integrated MCU and a specially designed metal oxide (MOX) gas sensor microplate, allowing for high reliability, fast cycle times and a significant reduction in the power consumption, compared to other MOX sensor-based devices. The Click board™ is also equipped with a temperature compensating element, which allows for increased measurement accuracy.
