{{dbox-gray|The graph here above shows the accelerometer X & Y axis value while turning the sensor. The value is return in multiple of ''g'' (so 9.81 m/s^2). As we can expect, the value on X and Y axis should go from -1 to +1 depending on the orientation of the sensor relative to the earth center. Any value outside of [-1..+1] range indicate an additional acceleration due my handshaking hand.}}
