Abstract

The tourism industry in Malaysia is one of the major leading sectors in economic development. Malaysia was once ranked 9th most visited country in the world by tourists. Tourism sector and air pollution are interrelated. Polluted air can negatively affect the tourism sector in return, the development of tourism sector can reduce air quality. High number of transportation and vehicles due to tourism activity may produce harmful gases that affect human health. This project aims to develop an IoT-based air quality monitoring system that provides air quality information at specific tourism areas through mobile application. This project has developed an air quality monitoring system by using MQ135 sensor to detect harmful gases in the air and used NodeMCU ESP8266 to able data deliver through Wi-Fi connection to IoT server. This system used BLYNK platform to create an app in the Google play store to allow tourists to view information about air conditions in the area they want to visit by downloading the app. The air quality monitoring system hardware would put at tourist spots, and the output from the sensor would remotely display on the BLYNK interface. In short, this project development divides into two parts, which are hardware development and software development. For hardware development, it involves a sensor, a microcontroller and Wi-Fi module called a sensing circuit and software development involves an IoT platform to create a mobile application. This system performance was tested by comparing data from sensing circuit with data from AirVisual application. As a result, the performance shows the sensing circuit ability to read air quality data same as AirVisual application and has the potential to be used as outdoor air quality monitoring system This project can help tourists to take care of their health and plan a suitable place to visit in accordance with their health conditions. The development system has potential to be commercialized as quality monitoring device for tourism purposes.
