I was wondering if anyone had a deeper idea about what units the PM2.5 Air Quality Sensor outputs in. I can see in the documentation I have the choice between “Standard”, “environmental” and particles per decillitre.
While the last one is quite obvious, I am trying to figure out what on earth the other two units are actually measuring in, unfortunately neither the datasheet nor google have been much help here, does anyone have an idea? I am hoping to compare to known measurements reported in micrograms per L.
Glad to see someone getting into particle sensing! I’ve been looking for a PM0.1 sensor for UFPs that come off printers for a while now, but can’t find one.
As for the specs, what sensor were you using? A link or SKU would be super helpful!
When I used one of these Plantower devices in a project I used the particles per 0.1L as it made more sense to me.
The Standard values I think, refer to a factory calibration or known environment.
The Environment ones refer to where the device currently is located.
The data sheet uses micrograms per cubic metre.
I think it is trying to give an indication of the weight of particles.
