Abstract
We have realized a multi-gas sensor array, which employs 4 different sensor materials: bare SnO2, and CuO films, and SnO2, and CuO films, functionalized with Ag- and Cu-nanoparticles. The sensors have been screened towards 6 specifics get gases (CO2, CO, NO, acetone, NH3, specific hydrogen carbide mixture) which are relevant for air quality monitoring in the harsh environment of mines. The sensing materials show specific response to the test gases, which enables an identification of the test gases by adjusting the operation temperature and applying a proper calibration method.
