AirGradient has created a DIY Air Quality sensor.
They offer a PCB, PCB + components kit, etc.
A pretty neat package.
To use this you have to run their software but you can use the kit with ESPHome as well!

Here is what it can measure:

- **Temperature**
- **Humidity**
- **Air particles PM2.5**
- **Carbon Dioxide**

Additionally:

- There is a display so show off your data or whatever you desire from Home Assistant
- You can download a 3D printable case including a wall mount bracket
