The CCS811 Air Quality sensor is an ultra-low-power digital gas sensor with an integrated MOX (metal oxide) gas sensor that can detect various VOCs (volatile organic compounds) through an integrated MCU (microcontroller unit) for indoor air quality monitoring.We use this sensor to detect VOC and CO2 levels in the environment.
The pins commonly used are: SDA, SCL, ADD, INT, WAK, VCC, GND.It needs to be explained here that SDA and SCL are relatively familiar, but INT and WAK are relatively rare. In this module, INT is equivalent to reset pin, and the SCM program integrated inside CCS811 chip can ground and reset the pin, and at the same time, SDA and SCL can communicate normally when WAK is at a low level.
So the hardware connection needs to connect the WAK pin to the low level,
