Evaluation kit for the CCS811 ultra-low power digital gas sensor
The CCS_EVK04 evaluation kit is designed to allow easy evaluation of
the CCS811 an ultra-low power digital gas sensor solution for
monitoring indoor air quality.
CCS811 supports intelligent detection algorithms to process raw
sensor measurements to represent equivalent CO2 (eCO2) levels or
TVOC measurement in real world environments, where the main
cause of VOCs is from humans. The result of these algorithms is
provided over a standard I
2
C digital interface.
The evaluation kit includes the following:
USB to I
2
C bridge board (CCS_EVK04_BRIDGE)
CCS811 Sensor board (CCS_EVK04_811)
USB to micro-USB cable
Windows based software for sensor measurements and
logging results
