<![CDATA[Servo motors play a critical role in precision control systems, traditionally relying on potentiometers for position sensing. However, potentiometers suffer from drift due to mechanical wear and physical contact, leading to measurement instability over time. This study investigates the implementation of Hall effect sensors as an alternative to potentiometers to mitigate drift in servo motor position measurement. The research methodology encompasses the design and implementation of a position measurement system utilizing Hall effect sensors, followed by a comparative performance evaluation against potentiometers. The experimental procedure consists of three key stages: sensor characterization, drift analysis under both unloaded and loaded conditions, and system response assessment to a reference angle. Performance metrics such as rise time, settling time, and steady-state error are analyzed. The results demonstrate that Hall effect sensors effectively minimize drift, offering improved stability, reduced position deviations, and faster response times in achieving target angles. These findings highlight the potential of Hall effect sensors in enhancing the accuracy and reliability of servo motor position measurement, particularly in high-precision applications.
