dc.description.abstractThe detection of volatile organic compounds (VOCs) is essential in practical application in breath analysis. Thus, gas sensors based on metal oxide have been fabricated, but they lacked selectivity. One approach to resolve this task is to use an array of highly sensitive and selective sensors as an electronic nose. Here a gas sensor array based on Tin oxide nano-structure with temperature modulation techniques was presented. A Platinum micro-heater is accompanied with the array gas sensor. The gas sensor array was composed of five single sensors, and that single sensor is located at different site from the micro heater and works at different temperatures. The gas sensing properties of the gas array sensors were investigated with VOC gases such as Ethanol, Methanol, Iso-propanol, and Acetone as well as NH₃, H₂, and H₂S. We also confirm the good selectivity of the array sensor for Ethanol, Methanol, Isopropanol, Acetone, NH₃, H₂, and H₂S by using radar graphic method.vi_VN
