PEMBUATAN ALAT UKUR MEDAN MAGNET PADA KUMPARAN BERARUS MENGGUNAKAN SENSOR MAGNETIK UGN 3503 BERBASIS MIKROKONTROLER AT89S51

Abstract

The measurement of magnetic field at coil have current base on the mikrokontroller AT89S51 have been made. This System can measure the magnetic field generated by bobbin emited a stream of the current and can be presented at seven segment. System consisted of hardware and software. The hardware consisted of magnetic censor UGN 3503, digital analogue to converter, mikrokontroller, seven segment to present the measurement data. Software consisted of the program use the Ianguage assambly which implementation at mikrokontroller. This system can measure the magnetic field at coil emited a stream of the current. This system have realized and can measure the magnetic field at bobbin have current with the measurement boundary 0 - 10 mT,with accuracy 1 mT
