Hello everyone! I am experimenting with MPU6050. I am working with Jeff Rowberg's library using DMP (MotionApps v2.0)). MPU6050 gives acceleration on x, y & z axis. I want to know, at what speed the object is moving. Please suggest the proper way for this purpose Thanks & regards.

Thanks for clarifying. I think, still, I am not getting it correctly so I need your help a little more. There are 2 sets of values, positive and negative. Both positive and negative values increase and decrease. Please explain the following. 1-Increasing positive value is definitely increase in velocity. What about decreasing positive values? Does it mean that velocity is still increasing but not as fast as it was increasing initially? 2-I thought that negative sign indicates opposite direction. You say, negative sign indicates deacceleration. If so, is there any way to detect motion in opposite direction? 3- What is difference between OUTPUT_READABLE_REALACCEL and OUTPUT_READABLE_WORLDACCEL

Hello everyone! I am experimenting with MPU6050. I am working with Jeff Rowberg's library using DMP (MotionApps v2.0)). I performed a simple test. For this test, I printed only y-axis OUTPUT_READABLE_WORLDACCEL values. As per my understanding, when mpu6050 is at rest, value should be zero. When movement starts, the values should increase. When stopped, values should decrease to zero but mpu6050 shows un-predictable values. These values are given below. 0 0 0 169 389 637 957 1388 2472 3025 3519 3937 4297 4563 4683 4704 4775 4815 4818 4848 4887 4903 4897 4856 4614 4383 4167 3951 3666 3348 3038 2685 2203 992 340 0 0 -313 -1363 -2355 -3223 -4627 -5346 -6057 -6644 -7120 -7407 -7513 -7582 -6995 -6578 -6178 -5841 -5422 -4872 -4459 -4063 -3125 -2664 -2253 -1942 -1531 -1248 -1064 -809 -270 -38 0 0 0 0 As I mentioned, I move the sensor from right to left. Above values show both positive and negative values which apparently seem to be two movements (i.e. from right to left and then from left to right). I am really unable to understand this pattern. Clearly I am missing/misunderstanding something. Please help me to resolve/understand this issue. Thanks & regards.
