Exploring the Indoor Air Quality in the context of changing climate in residential buildings. Part A: developed measurement devices of low-cost sensors
Indoor air quality (IAQ) is influenced by several parameters and the sources of indoor air pollutants are numerous (building materials, occupant behavior, HVAC systems, Outdoor air, etc.). Utilization of low-cost sensor devices for screening the indoor air pollution has made notable interests over the recent years. These systems are easy to access, portable, low-maintenance needed, and can provide real-time and continuous screening of target contaminants. The implementation of these systems to monitor the IAQ in real-time and for long period, can support the study of indoor air pollutants trends and variations. In this paper, we present sensors performance needed for an indoor air use. For this reason, four multi-sensor devices are fabricated and developed to measure O3, CO, NO, NO2, PM2.5, PM10, as well as the temperature and humidity, in an experimental measurement campaign study and were compared with results of a validated reference analyzers with high accuracy. The results showed a sufficient correlation of the measuring devices and the reference data considering the temperature and relative humidity. By the mean of Orthogonal regression method, the calibration equations were acquired for measuring parameters to enhance the IAQ monitoring devices performances. The results were examined on the basis of threshold limit value concentrations defined by European Commission indoor exposure limit values
