Abstract
Reliable detection of hypertoxic rocket fuel propellant – unsymmetrical dimethylhydrazine (UDMH) –with low rate of either false negative or positive signals in variable ambient air conditions by single temperature modulated semiconductor metal oxide sensor (MOX sensor) is presented. The applied sensitive materials are pure and Ru loaded nanocrystalline SnO2 made by single step technique, known as flame spray pyrolysis. The machine learning algorithm was used for raw sensor data handling and processing.
