Low-Cost Sensors And Indoor Air Quality: A Test Study In Three Residential Homes In Berlin, Germany
GEFAHRSTOFFE REINHALTUNG DER LUFT(2019)
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 O-3 with a commercial instrument based on low cost sensors in three private homes in Berlin, Germany.
