Design of 32-Channel Soil Moisture Meter Based on AD5933
摘要
Abstract
Based on the measurement principle of converting soil moisture measurement into electrical signal, this paper designs a 32-channel soil moisture meter which adopts STM32 as the control core and impedance con-version chip AD5933 as the measuring core. The system has the functions of automatic control,automatic cor-rection and supporting USB communication and so on. Results show that the measuring instrument has the ad-vantages of highly integrated circuits,easy operation,and high accuracy,stable and reliable performance, which may have wide engineering applications.关键词
