PENENTUAN FAKTOR KALIBRASI ACCELEROMETER MMA7260Q PADA KETIGA SUMBU
ABSTRACT: The features of
MMA7260Q are low cost, low current consumption, low voltage operation, high
sensitivity, a 1-pole low pass filter, and g-Select which allows for the
selection among 4 sensitivities. The accelerometer is an acceleration sensor
that output signal in voltage/g, where g is an earth gravity. The acceleration
is the rate of change of the velocity of an object and the velocity is the rate
of change of the position of the same object. The position is the integration
of velocity and the velocity is the integration of acceleration. If the data of
the acceleration of an object is known, the data of the position can obtain by
applied a double integration. This paper presents the calibration factor of
three axis of accelerometers. The value of three calibration factor are not
same. In general, the experiment using A1 algorithm and M2 method give the
smaller of error than the other. The calibrations factor are 2.1158 for x axis,
1.6873 for y axis, and 2.1539 for z axis. The error of the distance estimation is
about 3% till 4 %, so the research must be developed using the digital filter.
