Jim if the sensors are that cheap why not just use two mounted 90 degrees
apart. If its analog output you could just sum the two together to get
~total vibration or convert to digital feed a cheap microprocessor chip
and display all three. Logging all three channels would let you post
process the data all you want and would not be all that difficult.
