Abstract

Inclinometer based on the Microelectromechanical systems (MEMS) accelerometer has been applied widely in the heavy industry. However, this sensor suffers a considerable impact from external vibration. A low pass filter and moving average filter are the two most popular techniques to minimize this noise problem, but they still require other sensors to enhance efficiency. The paper proposes a Vibration Immunity (VI) filter which includes characteristics from both filters to minimize the noise optimally. A robust testbench was constructed by the Pan-Tilt Unit and a TUMAC vibrator to verify the proposed filters, implemented into a MEMS accelerometer LSM9DS1. The experimental result shows significant improvement after using the VI technique, respecting the moving average filter in noise reduction and stability.
