Smart Environment: IoT-based Air Pollution Monitoring System

Smart city technologies are transforming the way cities, councils and citizens interact, and internet-of-things (IoT) plays a crucial rule in enabling smart city solutions. LoRaWAN enables real-time analytics and reporting and can be used for a wide range of smart city applications such as smart environment, smart home, waste management, parking management and water metering. This project will focus on air pollution monitoring using a low-cost, low-power, long-range IoT system. 

 Driven by the recent advances in IoT, the project aimed to establish an IoT-based testbed to monitor the concentration of major air pollutant gasses and particles. The testbed is made of a gateway connected wirelessly to a variety of sensors forming a standard low-power network, which will be a typical example to explore the potential benefits of the fifth generation (5G) communication system that supports IoT applications. The sensors are placed strategically on top of Queens Building next to Mill Lane which has seen a remarkable transformation to a pedestrian-only road promoting healthier and more environmental-friendly approach to the area. The system is scalable and can be extended to wider areas or locations around Leicester with identified air pollution problems. In addition, it can be further extended to a variety of other IoT-enabled applications using relevant sensors, such as waste and recycling management, real-time parking spaces monitoring and allocation...etc.  Iot-smart-environment-870x800-img The LoRaWAN gateway for IoT applications on top of Vijay Petal Buidling, DMU campus, Leicester
