Responses of Consumer Grade Monitors to Residential Sources of Fine Particulate Matter
Brett Singer, Indoor Environment Group Lead, Lawrence Berkeley National Laboratory
Indoor quality monitors based on low-cost sensors are now available for under $300. These devices report measurements of temperature, relative humidity, and concentrations of one or more air pollutants. LBNL conducted experiments to determine how well these consumer-grade monitors detect and quantify concentrations of fine particles (PM2.5 and PM10) emitted from various common indoor sources. The output of low-cost monitors was compared to mass-based measurements using a Federal Equivalent Method and several research-grade light scattering monitors. This presentation will present results and discuss implications for using low-cost particle sensors to characterize and manage IAQ in homes.
