摘　　要：土壤湿度测量是21世纪农业发展重要的组成部分之一,合理的采集土壤水分含量对农业生产起着至关重要的作用,更利于人们合理运用农业资源得到更高的效益。本设计基于STC90C516RD+单片机进行数据的处理,利用高精度双路ADC7705进行数据的采集,保证数据的精确性,最后利用CH376U盘模块进行数据的存储,完成数据的超速存储,用户只需要将已经采集好数据的U盘接上电脑,即可实现上位机对所得数据进行分析和处理。利用时钟芯片DS1302可实时进行记录。Soil moisture measurement is one of the most important parts of agricultural development in the 21 st century,the reasonable collection of soil moisture content plays an vital role in agricultural production and it is more conducive for the rational use of agricultural resources and get higher benefits. This design makes data processing based on the STC90C516 RD single-chip computer and the high precision dual ADC7705 is used for data collection to ensure the accuracy of data,finally the data are stored using CH376 U module and the data storage of speeding is fulfilled. Users only need to have the collected data disk connected to the computer; the PC can be realized to analyze the data and processing. The clock chip DS1302 is used for real time recording.
