A Modular Indoor Air Quality Monitoring System Based on Internet of Thing

Abstract

With the problem of environmental pollution becoming more and more serious, people pay more and more attention to indoor air quality, because more than 80% of the time spent in the indoor environment. This paper designs an indoor air quality monitoring system based on Internet of Thing cloud platform, which adopts modular design idea and realizes the development process of the system quickly. The architecture design of perception layer, network layer and application layer of the system is given. Sensors can be connected to the communication gateway as long as they conform to Modbus communication protocol. The WYSIWYG (What-You-See-Is-What-You-Get) method is used to develop the interface of the monitoring system. Finally, the system is tested and analyzed. The test results show that the system runs stably and accurately, and supports remote monitoring of web and mobile versions.
