AQO passively displays the level of CO2 in the air #Feather #CircuitPython #ClimateChange #IoT #Adafruit
Via GitHub: Too much CO2 in the air affects how well brains function. The Air Quality Object changes color depending on air CO2 content. It’s meant to be a beautiful object which also passively displays information about the surroundings. It makes a normally invisible flow visible, so you can open a window when your air is getting stale.
AQO (Air Quality Object) by GitHub user qubist passively displays the level of CO2 in the air.
Install the code on an Adafruit Feather M0 Express by dragging the contents of the code folder (lib, main.py and helpers.py) onto the Feather’s CIRCUITPY drive. That’s it!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

The SGP30 has two sensors inside, the data sheet shows the sensitivity for hydrogen and ethanol (alcohol) with unstated discrimination between other gases. The CO2 ppm output is a calculated, approximate value based on a model of human respiration. It’s referred to as an equivalent CO2 (eCO2) value in the documentation on https://www.adafruit.com/product/3709.
The term "equivalent carbon dioxide" can be confusing since CO2e is often used as a measure of other gas’s greenhouse effect.
