user57476: I am trying to test how vibration waves move through different material...ie how sensitive certain components are.
I am needing a vibration sensor that will send me back some kind of measurement say in the form of an integer between 1 and (a number).
I have tried the 801S with an Arduino board and it was successful. The problem though is it just returns a 1 for vibration and 0 for none. To get the results I had to keep retesting and moving the material further and further away to get it to fail.
I also tried a HiLetgo piezoelectric analog sensor. It does return a number...but the results are all over the place...from 5 to 250. I have a device that supplies a consistent "tap" to be measured...so the HiLetgo had to be letgo.
I did research SE and found this question Vibration sensor for arduino but it does not answer my question.

user71575: I did some experiments a year or so ago to sense vibration through a (physical) office desk top using the inbuilt accelerometer and gyroscope of an Arduino Uno Wi-Fi Rev2. That chip is an LSM6DSM but I would think that any such module (e.g., MPU6050) connected to any Arduino could be useful.
There’s a good comparison article at Seeed Studios introducing vibration sensors for Arduino.
Update. Looking at the similar question linked by the OP I see several comments that the MPU6050 which I suggested  would have poor resolution. You may have to study data sheets (or experiment) to find the best  device for your purpose.
Second update. This white paper, “Measuring vibration with accelerometers” has some good engineering notes about selecting suitable accelerometers for different purposes.
