Active Buzzer Module

Self-oscillating sound buzzer module

The Active Buzzer Module with Internal Oscillator is an electronic sound device that produces a fixed beep when power is applied. Unlike passive buzzers, it contains a built-in oscillator circuit and does not require PWM signals or external frequency generation from a microcontroller. It is widely used in alarms, notifications, warning systems, timers, and Arduino-based electronics projects.
