The 3V Active Buzzer is a compact sound-producing device that generates a tone when powered by a low DC voltage, making it perfect for alarms, notifications, and feedback in electronic circuits. Being an active buzzer, it contains an internal oscillator, so no external signal is needed to drive itsimply supply the required voltage, and the buzzer will produce a continuous sound.
