Design and fabrication of real time air quality monitoring system based on web application

Air quality monitoring system that can monitor gas such as CO and SOx on ambient air in a real-time and can be accessed with internet line have been developed. Sensor element on this system is based on nano structured zinc oxide thin film synthesized using wet chemical route. Monitoring system is designed using arduino uno microcontroller as analog to digital converter, and ethernet shield for data transmission, computer server for database center and data acquisition. The data from this monitoring system can be accessed and viewed as web-page. The sensor element that used in this system is made at nanostructure so it will yield high sensitivity[1]. The optimum experimental parameters that will be used is temperature, exposure time to gas target, sampling period, and also ratio for regeneration time. Measurements will be held under well-controlled and artificially CO/SOx polluted atmosphere[2].
