low-cost PM sensors - R Subramanian

20-03-2018 · Note that the Wang et al. paper tests the sensors at concentrations in the 0.2-1 milligram/m3 range, or almost 100 times typical PM2.5 levels in the US. Now, (a) humidity can interfere with light scattering measurements which is how these low-cost sensors work; and (b) most aerosols grow in size with increasing humidity.
