Abstract

Abstract: This article introduces a new digital inclinometer . It is designed by the combination of MEMS sensors and LPC1114 which is popular with low-power, low-cost 32-bit cortex-M0 embedded microprocessor on the market. Kalman fitter the Digital signal output of MEMS accelerometer and gyroscope . Then calculate the inclination angle in degrees. Finally, transfers data to a remote server. The instrument is low cost, fast signal processing speed, and solar green energy. It has a small size, light weight, high accuracy and high precision. Then, it can be widely used in the tower tilting real-time monitoring of electricity, buildings, bridges and gravity reference system.
