Performance of low-cost monitors to assess household air pollution [dataset]

Raw data of PM2.5 and CO from an indoor wood-combustion experiment. We evaluated the performance of two low-cost sensors measuring fine particulate matter (PM2.5) (HAPEX Nano, Climate Solutions Consulting, and TZOA-R Model RD02, MyTZOA) and one measuring carbon monoxide (CO) (EL-USB-CO, Lascar Electronics Ltd.) in a real-world wood-combustion experiment. PM2.5 devices were compared against a DustTrak (Model 8534, TSI Inc.) and a BGI pump (BGI4004, BGI Inc.) and the EL-USB-CO data-logger was compared against a Q-Trak (Model 7575, TSI Inc.). Sampling was conducted in a single-family house in Terrassa (Spain) during five non-consecutive days. All devices were co-located 1 meter away from an indoor fireplace and 0.6 meters above the ground. Fire was set once per day with hardwood logs and kept burning for 12 hours including a minimum of 2 hours with an opened window. The data provided is the raw output from all the devices tested for the 5 sampling days aiming interested researchers to play with the data and reproduce our findings.
