Development And Research of an IoT WSN For Measuring Fine Dust Particles PM10 and PM2.5

This paper introduces a successfully developed and tested cutting-edge IoT real-time air quality monitoring system tailored for Smart Cities. The system is distinguished by its low energy consumption and relies on the combined use of LoRaWAN and GPRS wireless communication technologies. Its versatility allows for deployment uses both indoors and outdoors. Key components of the system include a single-chip microcontroller, air pollution sensors capable of measuring NO2, CO, PM1, PM10, and PM2.5 levels, as well as Long-Range (LoRa) and GSM modems. To ensure a sustainable power supply, a photovoltaic and a battery is integrated into the system. Additionally, the system features a graphical interface for presenting the collected information. The utilization of these technologies bestows the fine particulate matter measurement system with several notable advantages. These include cost-effectiveness, long-range communication capabilities, extensive coverage, prolonged device battery life, and straightforward operation. Overall, this system represents a significant advancement in real-time air quality monitoring, aligning perfectly with the objectives of Smart Cities and IoT-driven urban development.
