The SkySniffer drone was tested with a limited Ethanol release (200 ml/min) at ground level. The main objective of this test was to evaluate the influence of the drone itself on the detection and sampling capabilities. Despite the downwash of the drone and the 4 Bft wind, the release could clearly be detected by the electrochemical (EC) sensors and sampled with a vacuum canister.
When the data is plotted against the position of the drone on the map, the location of the release can be easily determined. Adding the altitude information of the drone to create a 3D picture, clearly shows that the release occured at low altitude
