Air Quality Monitoring Platform with the Integration of Dual Sensor Redundancy Mechanism through Internet of Things

Air Pollution is an environmental and a social problem which has harmful effects on ecosystems, climate, life expectancy and quality of life. It is counted in the largest environmental health hazards in the Philippines especially in the nation's urban areas. This study developed a platform that can monitor air quality in the Philippines wherein the environmental parameters being monitored are ambient temperature, humidity, particulate matter and carbon monoxide concentration levels. This study applies Dual Sensor Redundancy Mechanism to examine the validity of the sensor readings. Using Wi-Fi technology, the data obtained from the microcomputer is sent to the Cloud based Web Server. The output of the system which involves sensor readings and Graphical Representation with respect to time is displayed on the mobile application. After validating the prototypes, the percent difference obtained fall under 5% mark and by conducting Two-tailed T-test, it is determined that the prototypes are functioning correctly. The platform is also implemented in two remote areas and environmental conditions are compared using the data obtained during the monitoring process.
