Introduction
I bought this breakout board from Aliexpress.
The CCS-811 is an air quality sensor chip by AMS.
Pins:
- VCC connect this to 3.3V (!)
- GND to ground obviously
- SCL to ESP
- SDA
- WAK this needs to be low (!) in order for the chip to be active
- INT can be left unconnected
- RST can be left unconnected
- ADD can be left unconnected
My board was apparently configured at I2C address 0x5A.
