In this study, the design and fabrication of a micromachined LPD-based SnO2 gas sensor integrated with TaN micro-hotplate was carried out by utilizing MEMS technology. In the characteristics of the micro-heater, thermal response, thermal distribution and power consumption of heated TaN micro-heater were measured by FLIR systems. For the sensing characterization, the sensing responses of LPD-based SnO2 gas sensor with TaN micro-heater to H2S gas were measured in different operating temperatures. In sensing properties, the resistances of the gas sensor significantly change in the staircase concentration of H2S gas and which optimal operating temperature was 250 °C.
