Despite this thread, I want to use accelerometers for a bit of navigation this year.
In the attached excel spreadsheet, you can see that using the angles 0degrees 45degrees and 90degrees, I have found that the relation between the real acceleration and the output value is non linear and appears to be something like:
where a is the real acceleration and y is the sensor value.
1)How can I convert this to a more linear connection? (do i need to?)
2)How do I integrate the values over time to get speed and more importantly distance?
