Abstract:
The design and implementation of a magnetic field tester is crucial for accurate measurement and
analysis of magnetic fields in various applications, including industrial, scientific, and educational
environments. This project focuses on developing a portable, user-friendly magnetic field tester
capable of detecting and quantifying magnetic fields with high precision. The device is based on a
Hall-effect sensor, which is sensitive to magnetic field variations, providing real-time data on the
intensity and direction of the magnetic field.
The tester is designed with an emphasis on reliability, accuracy, and ease of use. It incorporates a
microcontroller for processing sensor data and an LCD display for visual output, allowing users to
observe magnetic field strength in both analog and digital formats. The system also includes a
calibration function to ensure consistent accuracy across different environments.
