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.
