The Continuation of a UAV Based System for Detection and Sampling of Micro-Plastics and Particulates in the Atmosphere 

In most recent years micro-plastics have become a heavily investigated topic. However, recent studies have shown a large increase in distribution of said particulates in more remote locations. Thus, the hypothesis that the movement of these microplastic is due to atmospheric channels. Therefore, within this paper we demonstrate and development of UAV Microplastics collection and sampling UAV. This UAV consist of a Integrated companion computer of which reads data from a SPS30 particulate sensor. Moreover, the UAV is also fitted with a custom particle filtration united used to collect ten separate samples at different altitudes.
