RESPIRABLE SILICA DUST MONITOR
Cryder, Sleeth, Zhang, Min, Zhang, Collingwood. University of Utah
Added Wi-Fi and other sensors but did not change how the sensor detected PM
Calibrate in the target environment
".. light scattering based instruments can yield consistent data for time-weighted average, full shift respirable aerosol concentrations. However the field experience indicated that attention needs to be given to the calibration of such instruments for each application, in full recognition of the influences of aerosol type and particle size distribution. Occupational hygienists should be encouraged but cautious."

Angela Jackson-Morris et al, 2016, Nicotine & Tobacco Research. "Many low- and middle-income countries (LMICs) have enacted legislation banning smoking in public places, yet enforcement remains challenging. The aim of this study was to assess the feasibility of using a validated low-cost methodology (the Dylos DC1700) to provide objective evidence of smoke-free (SF) law compliance in hospitality venues in urban LMIC settings, where outdoor pollution levels are generally high."
"This study suggests that low-cost air quality monitoring is a viable method for improving knowledge about environmental SHS and can provide indicative data on compliance with local and national SF legislation..."
In the early beginnings of the Dylos product, a UC-Berkeley researcher studied its performance. Able to precisely measure at high and low concentrations. From 1 ug/m3 to 1 mg/m3.
