FabLab - Smart Citizen Kit v2.1 (VOC)

General Description

The Smart Citizen Kit V2.1 (SCK 2.1) sensor provides real-time measurements of PM_1.0, PM_2.5 and PM₁₀ mass concentrations, volatile organic compound (VOC) and equivalent carbon dioxide measurements. The sensor also provides temperature, relative humidity, pressure, noise level, and ambient light measurements.

Principle of Operation

The SCK 2.1 sensor uses an integrated AMS CCS811 metal oxide gas sensor. An algorithm processes the raw sensor measurements to simultaneously report both a VOC and equivalent carbon dioxide concentration.
