| 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. |
