IoT and IAQ monitoring systems for healthiness of dwelling

The pandemic that we have been experiencing since 2020 has inevitably led us to consider renovating buildings, starting with internal comfort. Most Italian buildings were built before 1990. The performance conditions of the buildings are poor, especially those related to the well-being of the occupants (safety, ventilation, heating and energy efficiency). The COVID-19 pandemic has allowed to advance hypotheses of improvement of the buildings including monitoring of internal comfort through the use of sensors and the IoT. The paper aims to investigate indoor monitoring systems to increase the quality of life of occupants and proposes the design of a monitoring and control system to improve Indoor Air Quality. © 2022 IEEE.
