General Information

General Description
The
biosignalsplux tri-axial Accelerometer
(
ACC
) uses Micro-Electro-Mechanical Systems (MEMS®)
technology for the acquisition of high-quality accelerometery data. This sensor can measure
sub-milliG
accelerations and provides raw data of each axis on individual channels, giving you full control about
the acquired data.
ACC
sensors are commonly found in motion tracking applications where this sensor can be used for
the development of to measure physical activity, range of motion, as well as to conduct vibration
analysis, which, for example, can be used to prevent ergonomic injuries or evaluate tremors of
Parkinson patients.

Typical Unfiltered Sensor Output
Figure 2 shows a typical unfiltered
Accelerometer
sensor output acquired while doing an
8 like
movement in order to stimulate all axis. The raw digital sensor values received from the
biosignalsplux
device ranged between 0 and 2
n
-1 (
n=sampling resolution
) can be converted into the original unit of
measurement of this sensor (g) using the transfer function found in section
Figure 2: Typical unfiltered sensor output (doing an
8 like
movement in order to stimulate all axis).
