I am currently assembling a continuous Air Quality Measuring device as a Masterthesis.
So naturally, I have to dig a little deeper and ask a specific question.
In the description of the " Grove - Laser PM2.5 Sensor (HM3301) " it says:
"With specific mathematical model and algorithm, the count concentration and mass concentration of the dust particles is obtained. "
I could not find any further specifications about the algorithm or model, but they are crucial for scientific analysis.
As 2017 went by, the CEN has given out Standards for the validation of air quality devices. (read: EU Standard Methods for monitoring and UK Approach )
The one parameter, that I am mostly interested in is the volume of air that is taken for the Mass/Volume output of the HM3301.
Can anyone help me here?
Love from Berlin
