ABSTRACT Increasing attention has been paid to air quality monitoring with a rapid development in industry and transportation applications in the modern society. However, the existing air quality monitoring systems cannot provide satisfactory spatial and temporal resolutions of the air quality information with low costs in real time. In this paper, we propose a new method to implement the air quality monitoring system based on state-of-the-art Internet-of-Things (IoT) techniques. In this system, portable sensors collect the air quality information timely, which is transmitted through a low power wide area network. All air quality data are processed and analyzed in the IoT cloud. The completed air quality monitoring system, including both hardware and software, is developed and deployed successfully in urban environments. Experimental results show that the proposed system is reliable in sensing the air quality, which helps reveal the change patterns of air quality to some extent. INDEX TERMS Internet-of-Things (IoT), air quality monitoring, PM 2.5 , LPWA, IEEE 802.15.4k.
For the monitoring system proposed in REF , a Low Power Wide Area Network (LPWAN) was utilized to enlarge the network coverage to meet the communication requirements of a massive number of air quality sensors over a large sensing area.
