One of the pictures (http://www.robotshop.com/Images/xbig/en/dfrobot-digital-vibration-sensor-1-B.jpg) shows it connected to a "Roboduino I/O Expander. (http://www.robotshop.com/dfrobot-i-o-expansion-board-4.html
)"  

So based on those two pictures it appears

Pin 1:  Black  : GND
Pin 2:  Red    : D
Pin 3:  Green : +5V

Those colors really don't make sense (neither does an undocumented sensor), but that's the best I can tell without seeing an actual board.

Couldnt you use a piezo speaker to detect oscilliation?
