This study uses a microcontroller in tandem with SMS technology to effectively monitor the concentration of Nitrogen dioxide being emitted into the air by industrial firms. The present method being used by the Department of Environment and Natural Resources (DENR) requires much time, manpower and a controlled environment or laboratory. The thesis allows the government to monitor numerous industrial firms at the same time since data is gathered by the system and transmitted wirelessly to a database. It is programmed to send data three times a day on an eight-hour interval and when the maximum concentration is met or exceeded. It is also capable of sending data on demand to authorized personnel.
