Air quality sensing and monitoring

With growing transportation and population density, increasing global warming, and sudden climate change, air quality is one of the critical measures that need to be monitored closely on a real-time basis in today’s urban ecosystems. This paper examines the issues, infrastructure, information processing, and challenges of designing and implementing an integrated sensing system for real-time indoor and outdoor air quality monitoring. The system aims to detect the levels of gases, carbon monoxide (CO), carbon dioxide (CO2), temperature, and humidity on a real-time basis and provides an overall air quality alert. The development of the system for real-time monitoring and alerting is validated and supported through conducted experiments.
