Abstract

Pengukuran medan magnet guna mengetahu distribusi medan magnet pada suatu lingkungan merupakan hal yang penting di berbagai sektor seperti industri, rumah tangga,kesehatan, ilmu pengetahuandan teknologi, serta bidang lainnya. Penelitian ini bertujuan untuk mengukur dan memetakan distribusi medan magnet pada lingkungan sandbox menggunakan gauss meter yang dikembangkan sendiri dan memanfaatkan sensor Hall Effect Allegro A1302. Alat ini terdiri dari komponen utama berupa mikrokontroler Arduino Uno R4 Minima, modul ADC ADS1115, serta sensor Hall Allegro A1302 yang mampu mendeteksi perubahan medan magnet secara linier. Media sandbox dibuat dari akuarium yang diisi pasir silika guna meminimalkan gangguan eksternal terhadap pengukuran. Data diperoleh dengan melakukan pengukuran medan magnet pada grid dua dimensi dengan jarak 1 cm di seluruh permukaan sandbox, dalam berbagai variasi konfigurasi penempatan magnet neodymium, baik terbuka maupun tertutup pasir. Hasil pengukuran analisis menggunakan metode fitting distribusi Gaussian, dengan rata-rata nilai koefisien determinasi (R2) lebih dari 0.96 yang menunjukkan kesesuaian bentuk distribusi medan magnet dengan teori. Pengaruh ketebalan dan kedalaman pasir terhadap pembacaan sensor juga diamati dan terbukti memengaruhi hasil pengukuran. Penelitian ini membuktikan bahwa gauss meter berbasis Hall Effect dapat digunakan secara efektif untuk mengukur distribusi medan magnet secara spasial dalam lingkungan, serta menunjukkan sensitivitas sistem terhadap variasi medan dan posisi material magnetik.

Measuring magnetic fields to determine their distribution in an environment is im portant in various sectors such as industry, households, health, science and technology, and other fields.This study aims to measure and map the magnetic field distribution in a sandbox environment using a self-developed gauss meter that utilizes the Hall Effect sen sor Allegro A1302. The device consists of key components including the Arduino Uno R4 Minima microcontroller, the ADS1115 ADC module, and the Allegro A1302 Hall sensor, which is capable of detecting magnetic field changes linearly. The sandbox medium is con structed from a glass aquarium filled with silica sand to minimize external disturbances during measurement. Data were obtained by conducting magnetic field measurements on a two-dimensional grid with a spacing of 1 cm across the entire sandbox surface, under vari ous configurations of neodymium magnet placement, both exposed and buried in sand. The measurement results were analyzed using Gaussian distribution fitting methods, with an average coefficient of determination (R2 ) greater than 0.96, indicating a strong agreement with theoretical magnetic field distribution shapes. The influence of sand thickness and burial depth on sensor readings was also observed and proven to affect the measurement results. This study demonstrates that a Hall Effect-based gauss meter can be effective ly used to measure spatial magnetic field distributions in a environment, and shows the system’s sensitivity to field variations and magnetic material positioning.
