Decrease the chance of mold growth and contracting an illness while also increasing the comfort level indoors with this simple Arduino based air quality monitor.

This device filters dust and odors, and includes an Arduino and air-quality sensor to control the fan speed based on the air quality.

Make hardware and interface with sensors super easy using CircuitPython

Combining Adafruit’s CCS811 gas sensor with a Circuit Playground Express and two NeoPixel Sticks with a mask will monitor temperature, carbon dioxide, and total volatile organic compounds.
