    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
