Advantages and disadvantages of piezo?
Advantages:They generate a voltage proportional to the velocity the
crystal is deformed so require no local power source.
Disadvantages: They are high impedence and can pick up stray
voltages in the connecting wires. The crystal is also prone to
cracking if overstressed.
How to distinguish active and passive buzzer?
An active buzzer will generate a tone using an internal oscillator,
so all that is needed is a DC voltage.
A passive buzzer requires an AC signal to make a sound.
To identify them, if you apply a DC voltage to them and it buzzes,
it's an active.
