| Abstract | A frequency based sensor is presented to measure the conductivity of fresh water. A MEMS based conductivity sensor is designed to form the RC-Wien-Bridge Oscillator, and the conductivity of tested sample could be obtained according to frequency of the Oscillator by calibrating the frequency to the conductivity of standard liquid. In this paper, system description and electronic simulation are presented with an emphasis on the simulation of actual capacitance and frequency-capacitance characteristics of fresh water conductivity sensor. The results indicate the frequency range dedicated for fresh water conductivity measurement is from 90 kHz to 434 KHz. It is promising to measure the conductivity of fresh water with this kind of frequency based sensor. |

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.
