Hi there
,
while reading the sensor for acceleration I recognized some odd facts. The value for acceleration in z-direction easily rises to high numbers of over 20 and more. Am I wrong when I assume that simple dropping of my smartphone (by the way a Samsung S7, what is not important as I think) should give a constant value of 9.81 !?
When it hits the ground I could accept the rise to higher values, but not while falling.
For the 'acceleration with g' I have another question: Isn't this the simple addition of 9.81 to the experiment 'without g'. Because I wonder how it can be possible for a system wich does not change (on the floor lying smartphone) to measure any acceleration...
