Abstract
Air pollution has become one of the largest threats to the environment and human health
globally. However, the conventional approach of measuring air quality relies on a
limited number of stationary monitoring stations. This project aims to address this issue
and proposes building an air pollution measurement system based on an Unmanned
Aerial System (UAS). The project is divided into three parts: UAS design and
fabrication, sensor integration and testing. Firstly, a fixed-wing UAS was designed and
fabricated. The design and analysis were performed respectively and after the analysis
a detailed CAD model was developed, and the fabrication process was started. After its
construction, manual and autonomous flight tests were performed to ensure its
functionality. Secondly, the PMS5003 sensor was selected for measuring the particulate
matter while DHT-22 was selected for temperature and humidity measurement. The
sensors were calibrated using the reference device Laser-egg 201 with the assumption
that the data provided by laser-egg are accurate. A single-point calibration method,
which just adjusts the offset, was implemented. The final test was performed with the
sensor integrated into the UAS and the results obtained demonstrates the potential of
using UAS for air pollution measurement

Air pollution has become one of the largest threats to environment and human health
globally, being 4th leading factor for early death worldwide [1] and responsible for
death of 7 million people annually [2]
