Initial Development and Testing of Microcontroller-MQ2 Gas Sensorfor University Air Quality Monitoring
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 3
Abstract
Typical air quality monitoring system involved the use of expensive instruments often accessed through the Philippines Department of Environment and Natural Resources (DENR), leading to limitedlocale based air quality monitoring system. To address the need this study was conducted utilizing microcontroller (arduino-uno)-MQ2 gas sensor. The initial stage included preliminary development of premade devices, coding, and testing on site. The testing was conducted in the University of Science and Technology of Southern Philippines (USTP)-Science complex on March, 2017 with preselected dates. Result showed Rs/Ro ratio within the appreciable range for air quality. Overall, the study served as neo monitoring system for air quality locally and potential use can be maximized. However, it is preliminary in nature and needing improvement.
