IoT testbed for dynamic management of fine dust in indoor environments

Abstract

Indoor Fine dust and ultrafine dust problems are a threat to human health. To reduce this threat, it is necessary to work on ventilation, such as operating air purifiers or opening windows. The concentration of the indoor fine and ultrafine dust varies greatly from zone to zones depending on the indoor environment, such as the locations, sizes, and materials of furniture, window, people, computers, etc. However, we normally place and turn on the air purifiers, ventilation systems or circulators without considering the variations of dust densities in the indoor environment. By doing so, the highly concentrated dust zones will still likely to remain unpurified significantly threatening human health as well as the energy will be unnecessarily consumed purifying the purified zones. So, we need dynamically managing the fine and ultrafine dust considering the indoor distribution is necessary. We propose a oneM2M standard-based Internet of Things (IoT) system that can dynamically manage the indoor fine and ultrafine dust. We deploy the IoT testbed based on the proposed IoT system at the office. Furthermore, the useful insights gained from the testbed are provided.
