These work well at 3.3V, and are an interesting alternative to using a MEMS accelerometer to detect vibration. They are quite inexpensive, but they are also fully analogue which is quite useful for some applications. You would have to do some characterization testing if wanted to try to use these in a precision application.

My son and I are both drummers, so we ordered these Piezo sensors from DiGiYes for an upcoming project.The Good: - They are easy to use and do sense when you tap them. However, they do no pick up vibrations of taps (even hard taps) occurring right next to them.The Bad: - There is no documentation or datasheet provided. It appears there is a diode and resistor on the board, but there is no mention of them. There should be a resistor in circuits utilizing these types of sensors, so I wish there was some details about what is included on the board. - I don't think the sensors' readings are terribly reliable. I wrote a simple sketch that outputs their value when higher than a given threshold. I tapped on them consistently but would get readings anywhere from 150-850. There is no way some of my taps were 6-7 times harder than others.Overall, I think we can make them work for our project, but I'm not terribly happy with them.
