Abstract [en]
The research demonstrates for the first time the high selectivity of catalytic hydrogen sensors to other hydrocarbons (methane, propane, hexane, butane, ethane, and ethylene) at a temperature less than 70 degrees C. Two circuits were used to measure the response of the sensors: a Wheatstone bridge circuit and a divider circuit. Hydrogen measurement was conducted within a temperature range of 66-130 degrees C. The sensors exhibited high sensitivity (25-35 mV/%) and low power consumption (approximately 8.6 mW). The Wheatstone bridge circuit was observed to have the maximum value of selectivity and sensitivity.
