Abstract
A capacitive angular-position detective system is introduced.It takes the capacitive sensor as the sensing component
and the 89C51 single chip processor as the core.The characteristic
construction and working principle for the angular-position detection are presented in detailed
and the hardware block diagram and software flow chart are addressed.The experimental results show that the system measurement accuracy is ±0.05° when the angular-position changes range from 0°
