POWERLESS MOISTURE DETECTOR OF SOIL BY USING GALVANIC CELL AND MEASURING METHOD

摘要

The present invention relates to an unpowered device for measuring a moisture content of soil and a method for measuring a moisture content of soil which measure a moisture content of soil using a current value varying according to a moisture content of soil. The unpowered device for measuring a moisture content of soil is inexpensive, is conveniently carried, and can be widely used in gardening, farming, geological soil inspection, etc. The unpowered device for measuring a moisture content of soil uses a principle of a galvanic cell. The method for measuring a moisture content of soil uses a galvanic cell.
