The spec sheet curve parameters seems to stem from http://www.howmuchsnow.com/arduino/airquality/grovedust/ ("I digitized the Spec. Sheet Characteristic Chart and fit a cubic polynomial to it. I got the following equation: y = 1.1x^3 - 3.8x^2 + 520x + 0.62
")
In [Field calibrations of a low-cost aerosol sensor (Holstius)]http://www.atmos-meas-tech-discuss.net/7/605/2014/amtd-7-605-2014.pdf) Fig. 4 shows a comparison of lowpulseoccupancy (only range 0-4%) with PM2.5 of a reference measurement, which is more like P2=5+(330*lowpulseoccupancyP2)
with P2 unit [µg*m^-3]
