MEMS accelerometers offer easy integration and reduced cost to an emerging class of vibration monitoring applications. In addition to the many attractive attributes of the core sensors (size, power, multi-axial, analog and digital options, etc), more advanced solutions, such as the ADIS16229, provide a more complete solution that includes signal processing and communications. This type of programmable device can wake itself up periodically, capture time-domain vibration data, perform a Fast Fourier Transform (FFT) on the data record, apply user-configurable spectral analysis on the FFT result, offer simple pass/fail results over an efficient wireless transmission, provide access to data and results, and then go back to sleep.


New adopters of vibration sensing are finding that quick deployment and reasonable cost of ownership are good reasons to evaluate fully integrated MEMS devices.  For this reason, many engineers are considering MEMS solutions for new vibration applications.  For this reason, we decided to write an introductory article that describes the basic functions in a MEMS vibration sensor along with some key application-level functions.
