Gas detection and Sampling

Drones are often required for tasks that are categorized in the “three D’s”: Dull, Dangerous and Dirty. The SkySniffer drone is no exception, as it is developed for the detection and sampling of suspicious gasses. Its sensor suite contains a number of electrochemical sensors, amongst which a LEL (Lower Explosive Limit) sensor and a Photo Ionisation Detector (PID). The data from these sensors is sent in real-time to the ground control station to create an overview of the contents of the air surrounding the drone. Based on this sensor data, the pilot of the drone can decide to take an air sample in one of the vacuum canisters or in one of the adsorption tubes. These air samples can be processed with a GC-MS in order to identify the different substances in the air sample.
