I would like to program a MCU to be able to detect water flowing through a pipe. The requirements are:
1.) No tapping into the piping system (it should be an external device only).
2.) It should use the principle of sound measuring (audio quality does not matter).
3.) It should only detect sound emitted from the object it is in contact with.
So - I was thinking of using a piezo from a buzzer. I need help in choosing the correct piezo, I am not sure whether I should be using an internal or external drive piezo. I want it to be very sensitive. Are there any suggestions to what kind of piezo I should be looking for or specific parameters of the piezo I should be looking for?
Thanks in advance
