摘要：

In the present work, a simple and low-cost instrument is designed to measure the dielectric constant of ceramic materials using the impedance analyser IC AD5933. The AD5933 is highly accurate impedance converter, which provides the impedance value of the sample with respect to different frequencies. The capacitance and dielectric constant values of the prepared samples are derived from the impedance. A PIC microcontroller is used to interface the circuitry of the impedance analyser and display the measured data on the LCD. In addition, the measured data are exhibited on the serial console of the microcontroller. The measured values were compared with standard impedance analysing device HIOKI-LCR Hi-tester353250.Graphical Abstract
