GENERAL DESCRIPTION
The biosignalsplux tri-axial Accelerometer(ACC) uses Micro-Electro-Mechanical
Systems (MEMS®) technology for theacquisition of high-quality accelerometerydata. This sensor can measure sub-milliG
accelerations and provides raw data ofeach axis on individual channels, giving
you full control about the acquired data.
ACC sensors are commonly found inmotion tracking applications where thissensor can be used for the development ofto measure physical activity, range ofmotion, as well as to conduct vibration
analysis, which, for example, can be used
to prevent ergonomic injuries or evaluate
tremors ofParkinson patients.

APPLICATION NOTESThis sensor requires a calibration to provide reliable measurements. The resulting calibration
values (𝐶𝑚𝑖𝑛& 𝐶𝑚𝑎𝑥) which are needed for the transfer function below are determined by
performing a very slow 360° rotation of the sensor around each axis to force the accelerometerto cross the gravity-imposed −1g and 1g.
𝐶𝑚𝑖𝑛& 𝐶𝑚𝑎𝑥 define the minimum and maximum RAW data values, respectively, registered in
the axis under analysis during the calibration protocol.
