One Customer use our ADXL345 to test their vibration acceleration and then figure out the displacement. Now they are asking us weather we can use this part(ADXL345) to measure the frequency of vibration or not. As ADXL345 is a triaxial(3X) accelerometer, if triaxial accelerometer cannot measure the vibration frequency, can they use an monaxial(1X) accelerometer to measure the vibration frequency? IF the answer is yes, can ADI provide the arithmetic or solution. Thanks a lot!
Ps: the product is similar with a Feeding controller, when the material was transporting，the controller will vibrate till the end. They use our ADXL345 to measure the accelerated speed.
