Question on Resolution #6

Closed VivekSM1992 closed 3 years ago

VivekSM1992 commented 3 years ago

Hello,

I couldn't find the resolution of the data on kaggle. I believe the data is in g. I assumed this as the resultant of GravityX,GravityY and GravityZ comes close to 1 and the gravity is 1g. However, in the other comment here it says 4096 LSB/g. I couldn't understand the comment.

Thank You!

Hey @VivekSM1992 As far as I know, the accelerometer of the iPhone 6 we used is this one: https://www.bosch-sensortec.com/products/motion-sensors/accelerometers/bma280.html

Resolution(in ±2g range): 0.244 mg
Sensitivity (calibrated) : ±8 g
