PERANCANGAN SENSOR HMC 5883L DENGAN MENGGUNAKAN ARDUINO UNO SEBAGAI PENDAMPING KOMPAS RHI PENUNJUK ARAH KIBLAT PADA OIF UNIVERSITAS MUHAMMADIYAH SUMATERA UTARA

Abstract

The level of accuracy of a measuring instrument is expected to be as good as it is expected to provide information that can be used as a reference and benchmark in research and applications in public life. The use of compass measuring devices in determining the direction of the compass and the location of the earth's magnetism may vary from year to year such as analog and digital compasses. Both offer good reading results with the same workings using magnetic north and south poles as a reference point. HMC 5883L sensor is one measuring tool that is able to detect the direction of the compass with the same way of working from analog and digital compasses. By using Arduino Uno as a microcontroller as a central control that is able to change the information received from the HMC 5883L sensor into a form of data that is easy to understand. HMC 5883L sensor was applied as a companion to the data from the RHI compass reading results at the OIF University of Muhammadiyah North Sumatra to get a more accurate Qibla direction by comparing the reading results of both. The results obtained from the measurement of the different degrees of qibla direction of the HMC 5883L sensor and RHI compass are 7o and this is still safe and good to be used as a companion to the RHI compass on the OIF UMSU
