Design of Air Quality Monitoring Using LoRaWAN In Human Settlement

The increasing population affects the increasing density of settlements and the decreasing open spaces that results the crowded activities are held in limited number of available public concourse. It causes the poor air quality in environment and influences health rates of society. For planning and developing better habitation that consider air quality aspect, the data of air quality needed. This study proposed the design of IoT based-air quality monitoring system using LoRaWAN for human settlement. It uses WisBlock Kit 4 produced by RAKWireless and the Bosch BME680 based sensor modules to measure air quality index, temperature, humidity, and barometric pressure. The design was evaluated by measuring coverage of LoRa network and the response time of monitoring website to display the air quality data. The evaluation found that LoRa network covered area had the stable RSSI value, that is approximately -100 dBm, and the SNR range value 0.8 – 8.2 dB. The measurement of response of monitoring website resulted 0.58 seconds as the average value. It means the website display the real time data. The result of this study can be implemented to urban and rural settlement with no WiFi requirement in it. For the future study, it can be used for planning and developing public open spaces in settlements that consider air quality aspects.
