PENGEMBANGAN SENSOR MAGNETIK MAGNETORESISTIF (MR) UNTUK APLIKASI KOMPAS ELEKTRONIK
Abstract: Today the much
needed electronic equipment that can enable people to perform the activity.
Making thecompass using the magnetic field sensor is a sensor HMC5883L. The
tool has been tested and calibratedusing a standard calibrator magnetic field
that is Teslameter FH51. In determining the direction the sensoris connected to
the Arduino Uno HMC5883L which is connected to a PC by running
softwareapplications based on Visual C ++. HMC5883L sensors rely
magnetoresistif effect with linearitysensitivity to measure weak magnetic field
of the earth. HMC5883L a field sensor element which isequipped with a set /
reset and compensation coils are integrated. In addition to the sensor element,
signalconditioning unit and a unit determining the direction is also necessary
to establish an electronic compass.The main function of the unit is a signal
conditioning and amplification of the sensor signal offsetcompensation. Both
compensation techniques can be implemented only by controlling an integrated
set /reset and compensation coils are HMC5883L. Calibration technique is also
associated with the disorder,declination and inclination shown. Will eventually
produce a complete compass system.
