Resumo(s)
This paper presents a low-cost and smart measurement system to acquire and analyze mechanical motion
parameters. The measurement system integrates several measuring nodes that include one or more triaxial
accelerometers, a temperature sensor, a data acquisition unit and a wireless communication unit. Particular
attention was dedicated to measurement system accuracy and compensation of measurement errors caused by
power supply voltage variations, by temperature variations and by accelerometers’ misalignments. Mathematical
relationships for error compensation were derived and software routines for measurement system configuration,
data acquisition, data processing, and self-testing purposes were developed. The paper includes several
simulation and experimental results obtained from an assembled prototype based on a crank-piston mechanism.
