Build an AQI monitor
You can build a compact air quality monitor with 3D Printing and CircuitPython.
Powered by the Adafruit Feather ESP32-S2 Reverse TFT and a PMSA003I air sensor, this build can monitor air quality in real time! You can even read CO2, humidity and temperatures with a SCD4x sensor.
The 3D printed case houses all the components to make a portable environmental monitor that you can even wear!
CO2 + AQI
The easy to read interface displays AQI levels along side three colored squares to visually show air levels.
NeoPixel LEDs mirror green, yellow and red AQI levels.
Display CO2, humidity and even temperatures in Celsius or Fahrenheit!
Adafruit IO + WipperSnapper
This project is also compatible with WipperSnapper, Adafruit’s no-code solution to IoT Projects.
With WipperSnapper, you can easily set up sensors and start logging data.
Adafruit’s WipperSnapper has support for the PMSA, so you can build projects without having to write any code.
