Development of Metal Detecter Using Hall-senor
홀센서를 이용한 금속탐지장치의 개발
Abstract
We have developed a metal detector, which was made with two Hall-senors. We could detect the minute variation of terrestrial magnetism by the metal detector and the detector was handy to carry because it had been runned by a dry cell. So it will be utilized in finding ferromagnetic substances buried in the earth.
