Abstract:

The present paper gives the detailed analysis of the relationship between Voltage and Capacitance. This conversion from capacitance to voltage is required for the interfacing of electronic microcontrollers. Detection of various dielectrics can be done by using an accurate low capacitance measurement system that can be used to measure small values of capacitances. This capacitance measurement system uses quad two-input NAND Schmitt trigger circuit for the measurement and this system is integrated with Arduino for data acquisition purpose. The Arduino interacts with software developed in the PC end through USB architecture and an attractive Graphical User Interface (GUI) based system is developed in the PC end to provide the user with real time, online display of capacitance under measurement.
