AIRTOR: A Portable Air Quality Monitor


Objectives: Detecting air pollutants is a key factor in combating the Air Pollution Phenomenon. This study focused on creating an innovative air quality monitor device with a mobile application that can track personal exposure to harmful air contaminants and harmful gases. Method: A specific System Development Life Cycle (SDLC) model was utilized in developing the system called Prototyping. This model iterates some phases before jumping to next phase. Furthermore, the system was developed through the integration of LCD display, dust sensor, gas sensor, temperature and humidity sensor, Bluetooth module, Arduino microcontroller and a mobile application. The device can display data readings independently that has a built-in Bluetooth sharing capability. This built-in sharing feature enables the device to share data to the android application the researcher developed independently. Result: To measure the over-all usability of the system, alpha and beta testing was conducted using International Business Machines (IBM) Computer Usability Scale. Results indicated a grand weighted mean of 4.93 and 4.81 respectively and both can be interpreted as highly usable. This results means the system adhered to the standard set by IBM in system development. Recommendation: Utilization of this device is highly recommended.
