ACCELERATION CALCULATION FORMULA
Acceleration = (Output Voltage -2.5V) ÷ Sensitivity
The sensitivity can be obtained from the theoretical value
of the technical parameters or the actual test
E.g: AKF390-02-T (± 2G measurement range, 0 ~ 5V output voltage range)
Acceleration = (4-2.5)/1.25 = 1.2g
Note: Gravity 1G exists in the vertical direction in the static state.
