CJMCU811 RevSpace

The CCS811 is an ultralow power digital gas sensor for monitoring indoor air quality. It appears what they accomplished is integration of a metaloxide gas sensor into a tiny package so it uses very little power and has a fast response. For example, the wellknown MQ135 typically uses 750 mW just for heating the sensitive MOX layer. The datasheet can be found here. It measures volatile ...
