Last year I worked on an ESP32-powered air quality monitor device with audio/visual alerts, but couldn't finish it due to RSI. Now I finally got around to documenting the last bits and uploading pre-built firmware binaries.

I should open the window. My #DIY #CO₂ meter went full tilt.

I wasn't satisfied with #Sensirion's #USB powered #CO2 traffic light due to its hardcoded thresholds, so I built my own using a #RaspberryPiZero with solderless #ZeroDongle, #I2C #BreakoutGarden Mini #pHAT, Sensirion #SCD41 CO₂ sensor breakout and the #Pimoroni #LEDShim. All parts available at https://shop.pimoroni.com except for the Pi which is sold out.
The code behind it is based on two library examples by @gadgetoid and available at https://github.com/xtaran/co2-led-meter under the #MITLicense.
