IoT-based air pollution monitoring system

Abstract

Air pollution seriously damages the ecological environment and affects the health of humans, animals and plants. In order to prevent and control air pollution, air quality monitoring has been proposed to accurately monitor the concentration of pollutants and abnormal conditions in a region, which can purify the air. However, conventional fixed monitoring stations are complex, expensive and power hungry, these characteristics lead to monitoring stations being unsuitable for most areas. Here an internet of things (IoT)-based air pollution monitoring system is reported including architecture, principles and monitoring objects, providing detailed information for effective environmental management. It manages the current status and trends of regional air pollution in a simple, portable and cost-effective way. The technologies and applications involved in IoT-based air pollution monitoring systems are also presented, contributing to the development of IoT technologies, cloud computing technologies and smart city. The rapid spread of such monitoring systems would add greenhouse gases, photochemical smog and light detection and ranging (LIDAR) gases to the group of objects to be monitored in the future.
