21. The Accelerometer is a 3D accelerometer In general accelerometers have some kind of a piece of mass that is connected to a flexible material and a damping material The mass is pushed against the flexible material by the acceleration and the excitation is proportional to the acceleration The damping material prevents oscillation As a consequence the output is for low frequencies proportional to the acceleration For higher frequencies the sensor becomes less sensitive this is true for all types of sensors and there will be some phase shift this is also true for all types of sensors The bandwidth is 150Hz for the Z axis and typically 350Hz for the X and Y axis The analog output signal is sampled with a user adjustable sampling rate ranging from 10Hz to 1778Hz for all axes combined There is no anti aliasing filter which means that the user must be sure that acceleration doesn t oscillate with a frequency higher than half the sampling frequency For example If the sampling frequency is 10Hz for one axis then e g the wingbeat of a bird should not be more than 5Hz otherwise the user will get the wrong wingbeat frequency during analysis All XYZ axes are perpendicular to each other like a cartesian coordinate system The acceleration of the e obs Tags can never be used to predict positions by using exact mathematical or physical methods like integration because you have to mathematically integrate twice to retrieve position from accele
