Description
The 5V Mini Piezoelectric Passive Buzzer is a small, reliable sound-generating component used for audio alerts, alarms, and tone output in electronic circuits. Being a passive buzzer, it does not generate sound on its own; instead, it requires an external square wave or PWM signal to produce a continuous beep, allowing flexible tone control.
This buzzer is widely used in Arduino and ESP projects, alarm systems, timers, notification circuits, and educational electronics. Its compact size, low power consumption, and easy interfacing make it ideal for embedded and prototyping applications.
