How do you find the angle of an accelerometer?
The accelerometer measures the value of ′, which represents for the weight of the earth's gravitational acceleration in the axial direction on the sensor board. The tilt angle of the axis ∝ with respect to the horizontal plane can be calculated via an inverse trigonometric function: ∝= arcsin ' .
How do you convert accelerometer data to angle?
Measuring Tilt Angle using One Axis
If you want to measure tilt in both x and y axis with a 2-axis accelerometer then you can simply use sin-1(a) where a is the output from one axis of the accelerometer.
How do you measure an angle with a gyroscope?
The outputs of the gyroscope are in degrees per second, so in order to get the angular position, we just need to integrate the angular velocity. The accelerometer can measure gravitational acceleration along the 3 axes and using some trigonometry math we can calculate the angle at which the sensor is positioned.
