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°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). Feedforward 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.
