Air Quality Box

This is a ESPHome powered (integrated with Home Assistant) in-door air quality meter with a display.

It measures:

  • CO₂ concentration
  • Relative humidity
  • Temperature
  • Atmospheric pressure
  • Air conductivity
  • Dust particles <1µm weight concentration
  • Dust particles <2.5µm weight concentration
  • Dust particles <4µm weight concentration
  • Dust particles <10µm weight concentration

Assembly

This project is split into three parts, each with it's own steps:

  1. Printed circuit board
  2. Firmware
  3. 3D printed case
