“…It is the intent of this technique to produce a low cost device that would be economically suitable for installation in residential size heat pumps and air conditioning equipment. This type of device would be used to monitor compressor, fan, or rotating equipment performance within the system [ 7 ]. The digital output of this type of device could be easily interfaced with most microprocessors used today in air conditioning controls.…”

This report describes the development of a low cost, digital Micro Electro Mechanical System (MEMS) vibration meter that reports an approximation to the RMS acceleration of the vibration to which the vibration meter is subjected. The major mechanical element of this vibration meter is a cantilever beam, which is on the order of 500 µm in length, with a piezoresistor deposited at its base. Vibration of the device in the plane perpendicular to the cantilever beam causes it to bend, which produces a measurable change in the resistance of a piezoresistor. These changes in resistance along with a unique signal-processing scheme are used to determine an approximation to the RMS acceleration sensed by the device.
