Paper Title:
The Design of High-Precision Capacitance Micro-Displacement Sensor
  Abstract

This paper presents a design method of capacitance micro-displacement sensor, based on the programmable capacitance-digital converter AD7746. AD7746 is controled by Single-Chip Microcomputer which gathers the variation of capacitance from the plates and converts it to the digital quantity.The SCM PIC16F877 connecting with AD7746 through the I²C bus reads the digital quantity converted by AD7746 through software programming, then transmits the data into PC through serial interface,in which the whole high-precision capacitance displacement sensor design is accompished.
