Automatic Digital Dielectric Constant Measurement System

Abstract One of the important studies performed in electrical and electronic device manufacturing industries is measurement of AC Conductivity of solids. Many components are required for measuring AC conductivity by using AC bridge. Frequency measurement is exploited in this proposed work to determine the capacitance of the sample using embedded system and astable multivibrator to measure dielectric constant. This proposed work is an effort to improve a less costly and easily available embedded board for the measurement of capacitance and dielectric constant of the sample under different parameters.
