碩士 === 國立勤益科技大學 === 電子工程系 === 100 === Wireless Sensor Networks (WSN) is necessary for an intelligent house in the future. This paper describes a non-contact thermometer by detecting an object’s radiant power. We will attempt to design a portable device for remote measuring temperature and then to develop a sensing node for WSN. A thermopile equipped with a lens was used to implement the performance. The detection range is from 0 oC to 300 oC. The average error is within ±3 °C. In this study, Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software plays an important role for designing thermistor linearization and data logging. This study may provide a useful reference for researchers attempting to increase quality of remote radiometry.
