Abstract
Indoor Air Quality (IAQ) is an essential requirement for improving building sustainability. In fact, indoor pollution creates serious problems for human health and occupants’ well-being. Considering that Europeans spend on average 90% of their time inside buildings, IAQ plays a decisive role in human health, especially for the most vulnerable groups such as the elderly and children. Concerning children and youth, due to the presence for long periods of time in school classrooms, they tend to be more susceptible to developing chronic diseases such as asthma, allergies, and respiratory problems or make these problems more increased. In these circumstances, to prevent the occurrence of these specific illnesses, it is essential to improve the school environment, namely, classroom(^\prime )indoor air quality. This research aims to specify both the design and development processes of a LoRa-based IoT Edge device for classroom IAQ monitoring, by using low-cost commercial off-the-shelf components, capable of measuring relevant IAQ parameters specifically selected for a specific case-study analysis, namely the following: carbon dioxide (CO(_{2})), particle matter, and volatile organic compounds (VOC). At last, the prototype is delivered and assessed under controlled conditions. It is also worth highlighting that the prototype’s overall cost is approximately 150€.
