Owing to rapid urbanization and growing industries, there has been a considerable degradation in air quality, which affects both human health and the environment. Conventional air quality monitoring systems may involve high expenditure and may not be location-specific. Moreover, they may not provide real-time access to air quality data for all. To overcome these limitations, this proposed project focuses on developing an IoT-based air quality monitoring system with a Java-based web application .The designed system has the capability to continuously monitor important air-quality factors such a s particulate matter (PM2.5), carbon dioxide (CO2), and other dangerous gases with the help of low-cost sensors and a microcontroller interface. The sensor information is sent to a centralized server on a wireless platform. A Java server is designed to manage and monitor the received data, with a web interface to track the data online. This will provide a reliable and efficient solution to monitor the air quality in the urban area, campus, and public spaces. Therefore, through the real-time access to the air quality data provided by the proposed solution, the decision to enhance the air quality and health of the public can be made. The project shows how the combination of loT platforms with Java-based software platforms could be used for smarter and more sustainable environments monitoring systems useful for campus / urban areas available.
