I am working with MPU6050 (accelerometer + gyroscope). Concerning about the accelerometer;
Do these sensors(accelerometers in general) uses g as 9.8 m/s^2 or - 9.8 m/s^2 ? (Is there a standard/convention about this)
When I accelerate it in +x direction for example, it gives me a positive multiple of g, so I conclude that g should have be taken as positive.
But wanted to be sure by asking.
You can also clarify for me that whether it measures gravitational acceleration or the acceleration because of the normal force while standing horizontal(xy plane is level) on a flat surface for example.
Edit : I don't think this as a duplicate of my other question, this question focuses on one thing, the accelerometer outputs are designed considering g = + 9.8 m/s^2 or - 9.8 m/s^2.
