Hello, this is my first experience in this forum. :)
I was wondering if someone can help me understanding my accelerometer data installed in a project consisting in an object that is dropped in the air from an altitude of approximately 1000 meters. The descent is controlled by a parachute.
Well, while at the ground level I am getting the normal values witch are 0m/s2 for X and Y axis and 9,8m/s2 for Z axis. So when the object is dropped I get readings in the Z axis from 11 to 14 m/s2 (average 12.2m/s2). This value seem to be not consistent with my idea that a falling object with a parachute cannot have an acceleration grater then gravity acceleration.
Can anyone help me with this?Thanks a lot, in advance.D Cot@PS-I am sorry about my English.
