Design and Deployment of an IoT-Based Air Quality Monitoring System

Air quality is getting worse worldwide, especially in cities with high population density and many industrial parks. Raising community awareness and applying science and technology are effective ways to mitigate the negative impacts of industrialization and pollution on the natural environment as well as public health. This work presents the design and deployment of an IoT-based air quality monitoring system, named the Environmental Monitoring System (EnMoS). LoRa (Long-Range) wireless communication technology and innovation sensors being used aim to facilitate the development of data communication network over a large area, improving sensing reliability, extending battery life as well as reducing total system costs. The air quality factors such as particulate matter (PM2.5 and PM10), carbon dioxide (CO2), air temperature and humidity, after being read from the sensors were uploaded to a real-time database server for Air Quality Index (AQI) calculation. In addition, for indicating conveniently obtained AQI values a web page is also developed to provide an interactive map along with corresponding charts. A case study on an actual LoRa network consisting of three sensing nodes and a gateway were conducted for validating the feasibility of the system.

Environmental Monitoring System

This paper presents a reliable and low cost environmental monitoring system. The system uses an Unmanned Ariel Vehicle (UAV) equipped with a set of sensors, microcontroller, wireless system, and other accessories. The system consists of two systems namely air quality monitoring system and water quality monitoring system. The air quality monitoring system consists of a set of gas sensors and microcontroller. This system measures the concentration of greenhouse gases at different altitudes under different environmental conditions. On the other hand, the water quality monitoring system consists of a set of water quality sensors, microcontroller, and water sampling unit. This system collects water samples from off-shore and on-shore water sources and measures water quality parameters. The present system is capable of recording the measured data in an onboard SD card. It is also able to send data to a ground monitoring unit through a wireless system. To ensure reliability in measurement the sensors are calibrated before deployment. Finally, the system is upgradable and reconfigurable. The system has been tested to measure air and water quality at different local areas. Some these measured data are also presented in this paper.
