A review on indoor air quality monitoring system: a mechatronics approach

Abstract

Indoor air pollution directly affects mortality and also morbidity; it is also a vital issue of concern for the majority of nations that are in their developing phase. Coal and biomass (crop waste, wood, dung, and charcoal) are the main household energy sources for approximately around three billion people worldwide. Additionally, as most persons spend nearly 80–90% of their time in an indoor environment regularly, indoor air quality has a vital and direct effect on both general health and productivity of them. Although outdated, air pollution monitoring is nevertheless a very important idea in daily life. The monitoring of air quality has been done using both conventional methods and the most advanced computing techniques. However, as everyone needs access to clean air, many advanced wireless technologies have been used and some of them are quite helpful in giving information related to real-time data on air quality. The main purpose of this study is to describe some advanced techniques and devices used to monitor indoor air pollution and some of the significant advancements which have been done in this research field.
