I have MPU9250 IMU, which I am working on to get orientations from the sensor output data. While exploring the MPU9250 (also other sensor such as BNO055) datasheet I came across the full scale range for accel & gyro given as
±2 ±4 ±8 ±16 (g) and
±250 ±500 ±1000 ±2000 (deg/s). I did not understand what it signifies, but seems important.
I tried searching online related to full scale range but did not get explanation regarding it. I request if someone could help me in understanding by providing good explanation or a source which I can go through, I'd really appreciate that.
Also which one would be better to use?
I have asked the same question on Stack Overflow. I really need help on this.
