Abstract

Pengukuran medan magnet secara presisi sangat penting dalam berbagai aplikasi, termasuk industri, penelitian, dan pendidikan. Penelitian ini bertujuan untuk merancang dan membangun sistem pengukuran medan magnet berbasis sensor Hall Effect A1302 yang dilengkapi dengan metode kalibrasi menggunakan kumparan solenoida berinti besi ST41. Sistem ini mengintegrasikan sensor Hall Effect, mikrokontroler Arduino Uno, dan ADC eksternal ADS1115 beresolusi tinggi, serta menggunakan filter digital moving average untuk meningkatkan kestabilan pembacaan data. Proses kalibrasi menghasilkan hubungan regresi linier antara output sensor dengan medan magnet teoritis. Pengujian terhadap variasi jumlah magnet permanen menunjukkan respons linier sensor terhadap peningkatan intensitas medan magnet eksternal, memperkuat keandalan sistem dalam pengukuran praktis. Hasil kalibrasi menunjukkan koefisien determinasi R^2=0,996, menandakan tingkat akurasi yang tinggi antara pembacaan sensor dan nilai teoritis. Sistem ini terbukti mampu melakukan pengukuran medan magnet secara real-time dalam rentang ±50 Gauss dengan stabilitas dan akurasi yang tinggi. Selain itu, sistem memiliki keunggulan dari sisi kesederhanaan rangkaian, kemudahan pembuatan, dan biaya yang ekonomis. Oleh karena itu, sistem ini sangat layak diaplikasikan untuk kebutuhan pengukuran medan magnet di laboratorium pendidikan, penelitian dasar, maupun pengujian praktis di bidang industri.

Precise magnetic field measurement is crucial in various applications, including industry, research, and education. This study aims to design and develop a magnetic field measurement system based on the Hall Effect sensor Allegro A1302, equipped with a calibration method using an iron-core solenoid coil (ST41). The system integrates the Hall Effect sensor, an Arduino Uno microcontroller, and a high-resolution external ADC (ADS1115), along with a digital moving average filter to improve data stability. The calibration process generates a linear regression relationship between the sensor output and the theoretical magnetic field value. Testing with varying numbers of permanent magnets shows that the sensor responds linearly to the increase in magnetic field intensity, confirming the system's reliability in practical measurements. The calibration results yield a coefficient of determination R^2=0.9966, indicating a high level of accuracy between sensor readings and theoretical values. The system successfully performs real-time magnetic field measurements within a ±50 Gauss range, providing stable and accurate results. Moreover, it offers advantages in circuit simplicity, ease of construction, and cost efficiency. Therefore, this system is highly applicable for magnetic field measurements in educational laboratories, basic research, and practical industrial testing.
