Experimental Accelerometer Characterization

Author(s)

Abstract
This research describes methods utilizing LabVIEW software and a myDAQ device, a low-cost data acquisition (DAQ) device that gives students the ability to measure and analyze live signals from Bosch BMA145 accelerometers, both signals and noise. This tutorial instructs the reader how to setup the experimental test hardware and characterize an accelerometer and then proceeds to analyze the noise, permitting the utilization of the accelerometer for freefall detection (very useful to “safe” electronic devices in the event they are dropped) utilizing a novel algorithm that is a natural extension of the experiments used for accelerometer characterization and noise analysis.

Keywords
freefall, accelerometer; noise; fast Fourier transform, Bosch BMA145, LabVIEW, myDAQ
