Abstract
Various air pollutants harm human fitness, like particulate matter (PM2.5 and PM10), NO2, O3, CO, and fully volatile chemical-free compounds. In the last decade, international organizations have continuously worked to keep the Air Quality (AQ) guidelines and standards updated and refined to synchronize AQ modeling and management. The present AQ standards and guidelines have been provided by different agencies, including the California Ambient Air Quality Standards (CAAQS), the National Institute for Occupational Safety and Health (NIOSH), the Ambient Air Quality Standards (NAAQS), the American Conference of Governmental and Industrial Hygienists (ACGIH), the World Health Organization (WHO), and others. Various existing sensors for AQ management and analysis, their corresponding specifications, supply current, response time, data resolution, typical detection domain, measurement repeatability, or tolerance are issues of concern. These parameters are discussed to inspect present data research techniques focusing on indoor AQ. This study aims to provide a quick overview of AQ monitoring systems. These include portable, low-cost sensors and various international guidelines and standards for AQ management. Current trends and future scope are also presented after the discussion.
