Air Quality Measurement Device Using Programmable Quadcopter Drone Towards Internet of Drone Things

초록

Air pollution is a condition in which air quality is damaged and contaminated either by harmful or harmless substances for living beings. That is the reason why smart cities monitor the air quality. However, the installation for air quality measurement system is mainly in an area where there is a lot of pollution from traffics. This research proposes air quality measurement system over the ground using programmable quadcopter drone towards Internet of Drone Things. The sensors used to measure the air quality are MQ-135 and DHT22. NodeMCU is used to process and send the measurement value to Firebase, which can be further monitored by smartphone in real time. Air quality measurement test was carried out in two places, location 1 is the one with quiet environment and surrounded by trees, and location 2 is a very busy place surrounded with construction sites, each with 3 different altitudes (0, 3, and 5 meters) and 4 different sampling time (09.00, 12.00, 16.00, and 21.00). The system shows that higher altitude (5 meters) gives better air quality index compared to on the ground measurement (0 meter). Morning time gives better air quality index compared to other sampling time, even at nighttime, especially where there are lots of free surrounding the environment.
