Introduction

I bought this board from Aliexpress, it's a breakout board for the AMS CCS-811. The CCS-811 is an ultra-low power digital gas sensor for monitoring indoor air quality.

The datasheet can be found here.

Hardware

Pins on the breakout board:

  • VCC this is directly connected to the IC (there is no voltage regulator on board), connect this to 3.3V
  • GND to ground obviously
  • SCL signal from I2C
  • SDA signal from I2C
  • 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. I'm wiring it up to a Wemos D1 mini board with an ESP8266.

Software

I found two libraries:
