| dc.description.abstract | In this project, a measurement and detection system to detect tilt angle signal and vibration signal using MEMS accelerometer which has two sensed axes X and Y was successfully developed. Several issues are considered while developing the measurement system such as sensor specifications, software used for programming, device for interfacing and the flexibility of the software used. In this system the sensor specification such as low pass filter can be adjustable for intended applications. This filter is used for reducing the noise from output signal MEMS. This filter uses a capacitor valued 0.47uF with bandwidth of 10Hz. The bandwidth needs proper setting in order to improve the resolution and range of dynamic output signal. Available systems usually use different device and software for different tasks such as acquiring the output signal, processing and displaying the data into a meaningful signal. In this project the developed measurement system uses software which enables it to perform those tasks simultaneously. Moreover, the developed system can be easily set for signal acquisition. From the experiments carried out, the developed tilt measurement system can successfully measure tilt angle accurately from 0° to 90°. The measured tilt angle signal are compared with real sensed angle, and the results are also compared with equation. The measured vibration signal and the reliability of vibration measurement system developed in this project are compared with commercial device IMC-CSSOOS. This vibration measurement system is tested under vibration frequency starting from 5Hz to 500Hz with 1000Hz, 5000Hz and 50000Hz sampling rate. The characteristics of the vibration signal measured in sinusoidal form including positive peak acceleration (ms·2 ), RMS value and the amplitude of frequency domain using Fast Fourier Transform technique are verified. In conclusion, a measurement and detection system using MEMS as a sensor to detect tilt angle signal and vibration signal is successfully developed. | en_US |
