What are the units and scale of PRO line data?

• The unit for EEG signals is microvolts [μV]
• Accelerometer +/- 4g
•  Gyroscope 2000 °/s
• Quaternion data [−1,1] unitless

Our amplifiers are true-DC amplifiers, and the raw EEG data is not filtered in any way. This means that all channels have an offset i.e. baseline which is not removed. 

We leave it up to you to choose what kind of processing is applied to the raw data.
