Topic: Ambient Weather PM 2.5 sensor

[OldAlaskaGuy]

I have purchased and installed this to complement my WS-1401-IP array. It was an easy install and links through my Weather Observer IP bridge. Data is sent to Ambient Weather network. Sensor information here: https://www.ambientweather.com/ampm25.html
My station dashboard is here: https://dashboard.ambientweather.net/devices/public/cb606b61152ec0de5b4e6d97c5ab8af7
This sensor is very similar if not the same as the one from Ecowitt.
**EDIT** corrected dashboard address

Hope it does well for you. Yes it is the same as the Ecowitt with some minor differences internally (software). The Ambient version is the only one that will work with other Ambient consoles. The Ecowitt version only works with Ecowitt consoles. But the Ambient version will also work with Ecowitt consoles (from what others have reported) as long as the frequency matches. They are all made by Fine Offset.

I am trying to get an answer as to what a PM 2.5 sensor will monitor. I know pollen and dust are monitored but will it track gasses such as O3? I am aware of the issues with humidity, dew and moisture collecting partials causing spikes. I can see spikes around 11-2 at night this is also when we get our highest concentration of O3 where I live.

Dust and Pollen are up to your PM10 range, PM2.5 goes to a finer particle or smaller.

To my understanding most consumer level products do not have an Ozone (O3) sensor (Gases)... (Unless you pay premium)
And note that they are not in the same particle spectrum (Gas).

Ground-level ozone (03) needs a whole different sensor. In many areas of the U.S. the critical air pollutant is ozone, not particulate matter, especially in hot sunny weather.

It is also erroneous to call a PM sensor reading "air quality." Air quality and the Air Quality Index (AQI) depend on a combination of pollutants, not just PM, so if you are measuring just one pollutant you really cannot calculate an AQI number.
