| Abstract | The aim of this research is to develop vapor sensor system which works at room temperature. The development of system was used to test vapor sensing properties of tungsten organometallic-PANi thin film towards isopropanol and ethanol vapors. Tungsten organometallic solution was prepared by sol gel method. Commercial PANi powder were directly added into tungsten organometallic solution to form composite solution. Five layers of the solution were deposited onto $SiO_{2}$ coated silicon substrate using spin coating technique for fabrications of vapor sensing device. The vapor sensing test revealed that the composite film was responsive towards isopropanol and ethanol vapors with sensitivity of 5.58% and 4.76% each. The reversibility of sensor towards isopropanol vapor is 1.37 and towards ethanol vapor is 1.16. Meanwhile the response time for the sensor towards isopropanol vapor is 81 s and towards ethanol vapor is 108 s. The recovery time towards both vapors are same i.e. 189 s. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
