Abstract

The reduced air quality inside buildings is undoubtedly a key factor to be controlled to ensure the health and comfort of the occupants as people usually spend more than 90% of their time in indoor environments. This paper aims to present iAQ an automatic system that is capable to monitoring indoor air quality and send real time notifications to provide active coaching for occupants in order to improve indoor air quality. iAQ is a cost effective solution for indoor air quality monitoring and provide monitoring data access by a web portal and a mobile application. This system is equipped is a five cost effective sensors for data acquisition of environmental parameters (air temperature, humidity, carbon monoxide, carbon dioxide and luminosity). Other sensors can be added to monitor specific pollutants. iAQ assumes increased interest due to the use of low cost and open source technologies. In fact, iAQ system has advantages in terms of simplicity of installation and configuration, through the use of wireless technology.
