Accuracy Improvement of MEMS Using Accelerometers for Gravity Measurements

Micro-electromechanical systems (MEMS) accelerometers are widely used in various applications, including gravity measurements. However, their accuracy is often limited by factors such as noise, temperature sensitivity, and calibration errors. This study presents methods to enhance the precision of MEMS accelerometers in measuring gravitational force. By implementing calibration techniques, noise filtering, and temperature stabilization, we achieved a significant reduction in measurement errors. Experimental results demonstrated that addressing low-frequency noise and temperature variations improved accuracy to slightly over three decimal places, making the system suitable for high-precision applications such as digital inclinometers. The findings indicate that while MEMS accelerometers can be optimized for more accurate gravitational measurements, achieving even higher precision requires further refinements in noise reduction techniques.
