REVIEW ON INDOOR AIR QUALITY MONITORING SYSTEM

Abstract

Smart cities follow different strategies to face public health challenges associated with socio-economic objectives. In smart cities, buildings play a key role and are closely linked to the wellbeing of people. In addition, they are equally important in order to achieve sustainability goals. Indoors, people spend much of their time. Indoor air quality, therefore, has a vital influence on health and well-being. With the rising elderly population, the promotion of occupational health and well-being needs environment-assisted living systems. In order to detect unfavorable indoor quality scenarios in useful time, living environments must also integrate monitoring systems. This paper reviews the current state of the art on indoor air quality monitoring systems based on Internet of Things and wireless sensor networks in the last five years (2014–2019). This document focuses on the architecture, microcontrollers, connectivity, and sensors used by these systems.
