Abstract
This paper presents how an array of sensors with different sensitivities to gases can be applied for detection of hydrogen in the presence of humidity when operated upon various temperature - induced profiles. The sensors in the array are subject to temperature modulation over the range of 350 - 500 degrees C. Temperature profiles are based on a cardinal sine as well as Meyer wavelet phi and psi functions. Changes in the sensor operating temperature lead to distinct resistance patterns of the sensors depending on gas concentration. The sensors responses are studied as a function of target gas concentration (0 - 3000 ppm) and relative humidity level (0 - 75%Rh). Feed-forward back-propagation neural networks are used in order to facilitate gas concentration and humidity level prediction. The results show reliable hydrogen detection upon temperature modulation and a reduction of the total power consumption.
