@Yonsm could you check if these devices also support same readings?

According to the data sheet:
I don't really understand how the device can measure "beyond 10µm" if that it's max range. What am I missing?

According to the data sheet:
This was my interpretation (read value * 10 for number of particles in 1L)

Yes, I understand the same, but you have defined the units per square meter of air when it should me per liter, so magnitude_particles_m3 should be magnitude_particles_l
