Recommendation for Outdoor Air Quality monitor?

Looking for an Outdoor Air Quality monitor.
According to WHO the most common pollutants outdoor are:

  • PM2.5 (particulate matter 2.5)
  • CO (carbon monoxide)
  • O3 (ozone at ground level)
  • NO2 (nitrogen dioxide)
  • SO2 (sulfur dioxide)

But I can not find any air quality monitor covers at least half of this.
The only monitors I found measure just PM2.5 and some basics which is not so important for outdoor (like CO2 or indirect TVOC etc).

I bought AirGradient Outdoor monitor, but it’s pretty useless, since it measures only PM2.5 and even temperature & humidity are not accurate.
I tried Airthings View Plus but it is even worse: only PM2.5 measurement + non replaceable sensors inside + overprice + originally indoor only

Does anybody have recommendations for outdoor Air quality monitor?

Hi,
Cheap and basic might work outside if sheltered:

For more coverage of custom sensor types, I’d personally look at ESPhome + ESP32 + I2C sensors like (scroll down past the PM2.5)…

There’s quite a range that can plug together with STEMMA QT / Qwiic / Grove (I2C plus some GPIO) connectors to give you the desired coverage.

In theory, you can plug these sensors into a HA Voice, but that would be a bit of a waste outside.

If this helps, :heart: this post!
