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