Abstract

There are surprisingly few representative data sets available on particulate matter (PM) and inorganic pollutant gas concentrations for indoor environments. Meanwhile, there is an increasing trend to use low-cost sensors in air quality studies, which may introduce new kinds of investigations. It is, however, unclear whether low-cost instruments can provide enough precision and long-term stability to quantify the comparatively low pollutant concentrations encountered in office and residential indoor environments. This work reports test measurements of PM2,5, CO, NO, NO2 und O3 with a commercial instrument based on low cost sensors in three private homes in Berlin, Germany.
