No. The ADXL362 has no high-pass filter; that is, it measures acceleration down
to DC and can therefore be used as a tilt sensor, using the response of each of
its axes to gravity.
Sometimes it is desirable to eliminate the effect of gravity for activity and
inactivity detection. For this purpose, a referenced mode is available for both
activity and inactivity, that compares acceleration to a calculated reference
rather than an absolute threshold. The reference is based on the initial
position, so activity or inactivity are detected based on a change from initial
position, thus negating the effects of gravity.
