IOT System for Smart Air Quality Measurement

Air pollution has become a major concern due to the rapid growth and development of cities. In order to assess the level of air pollution, it is necessary to continuously monitor the air quality, so that preventive measures can be taken. This paper proposes the design of a smart air quality monitoring system using the Internet of Things (IoT) technology, where low- cost sensors are utilized for continuous monitoring. The system measures, processes, and analyzes air quality information by combining gas sensors with a microcontroller and cloud server. To allow remote monitoring the key parameters such as carbon dioxide (CO), carbon monoxide (CO), and dangerous gases are to be identified and transmitted wirelessly. The system is useful for industrial, smart city, and public health applications because it provides accurate and update the information on air quality. The proposed approach is highly effective for continuous assessment of air quality.
