How does the driver know to drive the piezo vibrator only when it is covered with water?

I dont know but it did not work for me at al. Had to throw the humidifier out. I tried 2 different pieces...same result. I wouldnt trust this at all.

Hello, how thick is the seal/gasket? Does it hold the disc at an angle?

With my humidifier I had to use my gasket/seal, and it lays flat.

What voltage is needed?

Hello,Mine was for an essential oils diffuser. I don't know a lot about electronics but I know this hooked into a 12v fan and power source. Hope this helps🤔
