Web3]. In metal oxide gas sensors, micro-heater is used as a hot plate which controls the temperature of the sensing layer. This type of gas sensor utilizes semiconductor properties of surface adsorption to detect changes in resistance as a function of varying concentrations of different gases. In order to detect these resistive changes, the heater temperature … WebAbstract Semiconductor gas sensors based upon n-type WO3 nanoparticle powder were fabricated and their response from 100 ppb to ppm levels of H2S in air has been investigated. In this study, a low power MEMS based micro-hotplate was employed as the substrate and operated at a constant temperature of 350̊C. Experimental data … html glyphicon
