Developing a magnetic field tester plays a vital role in ensuring precise measurement and effective analysis of magnetic fields across a wide range of applications, including industrial processes, scientific research, and educational settings. This project presents the design of a compact and user-friendly device capable of detecting and accurately measuring magnetic field strength and direction. The system utilizes microcontroller (Arduino Uno) and Hall-effect sensor known for its sensitivity to magnetic variations, enabling real-time monitoring of magnetic field characteristics. The tester is engineered with a strong focus on accuracy, reliability, and operational simplicity. It features a microcontroller for processing sensor output and an LCD screen that displays the magnetic field strength in both digital and analog forms. Additionally, the device includes a calibration mechanism to maintain measurement consistency in varying environmental conditions, enhancing its dependability and precision in practical applications.
