In a typical raised-floor data center, the temperature of the free access floor is almost constant and lower than the server rack area. Using this characteristic of the data centers and the impulse response of the measurement system, a correction technique was developed to improve the spatial resolution of the temperature measurement. As a result, the relative error for the temperature difference on the door of the server-rack became less than 1/10 of the original distributed temperature sensing (DTS) measurement. The new technique made us possible to visualize the temperature distribution in data centers more thoroughly and accurately.","PeriodicalId":202062,"journal":{"name":"2011 Fifth International Conference on Sensing Technology","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124167011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oxidation occurs on the heated WO3 sensing layer as an aromatic hydrocarbon is present in the atmosphere, which causes a resistance variation of the WO3 thin film. From the measured resistance change, the aromatic hydrocarbon concentration is then computed. It is found that the crystalline structure is more perfect as the as-sputtering substrate temperature is 300°C, the WO3 thin film is annealed and the sputtering time is more than 6 hrs. At the optimal working temperature of 300°C, the experimental results show that the sensor has a rapid response time and a high degree of sensitivity for detection of benzene, toluene and xylene.","PeriodicalId":202062,"journal":{"name":"2011 Fifth International Conference on Sensing Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131064328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
