土壤含水量 測定用 Sensor 開發 = A Study on the Development of Soil Moisture Sensor

국문 초록 (Abstract)

본 실험은 성장과정중 토양의 함수량을 間斷없이 측정하기 위하여 석고블럭 sensor를 제작, 그 특성을 비교하고 측정 system을 구성하는데 목적을 두고 실시하였다.
1) 石膏 블럭에 埋設된 格子型 stainless steel 電極間의 거리는 3 및 6mm가 9mm에 비해 정확도가 높은 것으로 나타났다.
2) 格子型 電極의 幅이 측정치에 미치는 영향은 없었으나 石膏 블럭의 크기에 影響을 미치므로 5~10mm가 이상적이다.
3) 格子型 電極의 幅 10mm, 電極間의 거리 3mm의 sensor가 가장 이상적이었다.
4) 본 測定 system은 토양 함수량을 間斷없이 測定 가능하였다.

This study was carried out to determine the soil moisture content for a gypsum block sensor, which is easy to be applied to a computer system was developed to measure the soil moisture content. And also a measuring system was developed to record the measured value of soil moisture content continuously.
1) The sensor was more accurate when the distance between the lattic-type stainless steel elec trodes installed in the gypsum block were 3mm and 6mm than in the case of 9mm.
2) The lattice-type electrode widths dose not have any direct influence on the accuracy of measurement, but it determines the gypsum-block. So the ideal size of the electrode width is 5∼10mm.
3) When the size of the electrode widths was 10mm and the distance between the electrodes was 3mm, the sensor functioned most accurately.
4) The system developed for this study was capable of continuous measuring.
