Our group has recently published two articles on the evaluation of low-cost aerosol sensors. 

• Field use of a Dylos DC1100 to measure aerosol concentrations for months in a swine barn. Available Here. DOI: 10.1093/annhyg/mew009
• Laboratory evaluation of several sensors to measure aerosol at occupational concentrations. Available Here. DOI: 10.1080/02786826.2016.1162901
