Design Method of Tiltmeter based on MEMS Accelerometer

This article proposes a method of designing tiltmeter with MEMS accelerometer. The output signal of MEMS accelerometer is processed through A/D sampling. Then MCU is used to process the digital signal. Consequently, the obliquity can be measured with high precision. This method can the get value of obliquity within the range of ±180°. If the system circumvolves,the tiltmeter can also get the accurate value of obliquity. So it can be used to measure the pose of airplane missile and any other aerocraft.
