CCS811 Indoor Air Quality Digital Sensor Module

The CCS811 a gas sensor chip system chip (SSoC) + temperature and humidity sensor, using low-power sensing technology to detect indoor volatile organic compounds (VOCs).

CCS811 8118 board schematic structure of the figure we can see that this is not a simple sensor, it has integrated MCU, the sensor has an onboard processing capability, without host intervention, can provide the equivalent level of carbon dioxide or total volatile organic compounds (TVOC) index. At the same time, with the use of separate gas sensors and MCU solutions, CCS811 can save equipment inventory costs as well as up to 60% of the total area of the board.
