12mm Active Buzzer - 10 Pack
Do you need a simple, audible alarm output? Something almost ear-splittingly loud that can be driven from between 2 to 6 volts DC? Then these active buzzers from PMD Wa are for you.
Just feed it DC current - no need for PWM - and you're done. Do not put it too close to your ears, as the sound from the buzzer will hurt.
