    土壤温湿度测量仪的研制

    A Design of Instrument for Measuring Temperature & Moisture of Soil

    • 摘要: 为快速测量大田土壤温湿度,而设计的仪器,湿度测量采用电容法。非电量经A/D转换后,通过EPROM制表的方法,实现了数据线性化。温度传感器采用AD590。

       

      Abstract: An instrument is designed for rapid measurement of temperature and moisture of soil in field soil. The moisture is measured with capacity method. Measuring code was linearized after non-electric quantity was converted by anatlog-to-digital conversion and the EPROM tabulated data. An integrated temperature sensor AD590 is adopted.
