Dataset associated with "Effects of Aerosol Type and Simulated Aging on Performance of Low-Cost PM Sensors"

These data were collected during a study on the performance of low-cost particulate matter (PM) sensors. All data were collected in an indoor laboratory at Colorado State University in Fort Collins, Colorado, USA between 2019-07-02 and 2019-10-06. The files associated with this dataset include: (1) time-averaged PM mass concentrations reported by the low-cost sensors during each steady-state test point included in the study, (2) time-averaged particle number concentrations reported by the low-cost sensors during each steady-state test point included in the study, (3) time-averaged particle size distribution data measured using an Scanning Mobility Particle Sizer (SMPS) during each steady-state test point included in the study, (4) time-averaged particle size distribution data measured using an Aerodynamic Particle Sizer (APS) Spectrometer during each steady-state test point included in the study, (5) PM2.5 concentrations recorded at one-minute intervals by a Tapered Element Oscillating Microbalance (TEOM) during all experiments conducted during the study, (6) Arizona Road Dust concentrations recorded at one-minute intervals by a DustTrak during an experiment in which the low-cost sensors were exposed to very high PM concentrations for 18 hours, (7) data associated with all gravimetric filter samples of PM collected during the study, and (8) all of the raw data recorded by the low-cost PM sensors during the study.
