A smart sensor circuit board comprises an interface to a wireless smart sensor board platform, a multi-axis accelerometer having a measurement range and resolution set to provide sensitivity to measure ambient structural vibrations resulting from non-catastrophic routine environmental factors, an analog to digital converter (ADC) for converting signals from the multi-axis accelerometer having a plurality of individual channels including oversampling, filtering, and decimation, and each channel being individually programmable for gain, anti-aliasing, cut-off frequency, sampling, and frequency providing data to the interface, and a low noise and high sensitivity amplifier having the plurality of individual channels to receive signals from the multi-axis accelerometer.
