Air quality has become a serious concern from the world's leading universities. The campus as a learning area needs good air quality and needs to monitor and maintain it so that academics can engage in healthy and optimal activities. This study develops a system for monitoring outdoor air quality on campus by using a wireless sensor network (WSN). MQTT Protocol is used to maximize data transmission from sensor nodes to brokers via wireless local area network (WLAN). Air quality measurement data is reported in real time via a web server that can be accessed via the internet. Sensor nodes and brokers are built using open source hardware and software. The system is implemented for measuring air quality on campus and shows measurements that are accurate, real time, and can be accessed via the web. © 2018 IEEE.
