This paper presents the design and framework development of a low-cost IoT-based multi-param-eter air quality monitoring network for smart campus applications, including its hardware and software architecture and an initial evaluation of the proposed prototype. The proposed system is designed to measure key environmental param-eters, including particulate matter (PM1, PM2.5, PM10), ambient noise levels (dB), temperature and barometric pressure. The system is based on cost-effective hardware components and integrates wireless communication technologies to enable real-time data transmission. The system enables continuous monitoring while remaining user-friendly and easy to deploy. Unlike traditional monitoring systems, which rely on large and expensive equipment installed at fixed locations, the proposed system is compact and portable, allowing deployment across different locations and enabling users to monitor environmental conditions in real time, while also providing indicative insights into potential changes in measured levels. Experimental validation of the noise sensing module demonstrated good agreement with a reference sound level meter, indicating the suitability of the proposed system for indicative environmental monitoring applica-tions.References
