Abstract :
This paper introduces a low-power impedance measurement system design principle. In this system, it used a very low-power chip MSP430F149 as CPU, and adopted AD5933 which integrating ADC conversion, amplification and filtering functions to measure unknown impedance, then the datas will be send to PC control system through the serial interface, eventually, the impedance values measured can display on the man-machine interface.
