SG33 - VOC & eCO2 (CCS811)

Overview

This xCHIP is equipped to sense a variety of Volatile Organic Compounds (VOCs). This xCHIP is based on the CCS811 which is an ultra-low power digital gas sensor which integrates a metal oxide (MOX) gas sensor to detect a wide range of Volatile Organic Compounds (VOCs), for indoor air quality monitoring, a micro-controller unit (MCU), and an I²C interface.
