Vibration sensor for arduino I need vibration sensor for my project. I have found many sensors similar to this one. But it seems, that this sensor outputs only zeros for "non-hit" state and ones for "hit state". And I need something that can output levels of vibration, not only presence/abscense. 

So is there any high-resolution vibration sensor for arduino?

Thank you!
I assume the OP wants the frequency of the vibration, which an accelerometer such as the ADXL345 won't give.

I have two workarounds: if the expected vibration frequency is low, say, under 100Hz, use instead an on/off vibration sensor (adafruit has them for under a dollar) and count the number of transitions. If it's more, how about a microphone and a band-pass filter?
