More about CO2 sensors:

See RandeLab GitHub for Arduino / Teensy codes

Nondispersive infrared sensor

MH-Z16, available with an I2C board:

MH-Z19:

This page is about the MH-Z19 CO2 sensor and some experiments done with it:

Using the MH-Z19 CO2 sensor PWM readout, simple arduino code:

More on ABC, Automatic Baseline Correction

Immerhin kann man den Sensor per Hd-Pin (7s gegen GND) auf 400ppm (Außenluft) eichen.

CCS811

CCS BME combo

This one I ordered 2.... but check I2C adress. and connect "WAK" to GND

  • #define CCS811_ADDR 0x5A //Alternate I2C Address
  • myBME280.settings.I2CAddress = 0x76;
