Hi,
I have a CHR-6D IMU with the pololu usb to serial adapter. I am trying to gather vibration data for a lawnmower so I need the accelerations in g’s for vibration analysis. I have the CHR-6d IMUKit PC application and I can get the raw acceleration data from there. The formula I use to convert raw data into meaningful acceleration is this:
Acceleration in gs= (Raw Data-512 ADC Units)/(102.3 ADC units/G).
But the problem is that this gives me some bogus answers in G especially in Y,Z direction. So the second method I tried is to get the data into matlab and analyze it there but I haven’t been successful. I was wondering if anyone has done this. I would highly appreciate it.
