Description

The Continuous Active Buzzer (DC 3V–24V) is a compact electronic sound module that generates a steady tone when powered. Unlike a passive buzzer, this active buzzer has a built-in oscillating circuit, meaning it produces sound automatically without requiring external signals. It’s ideal for alarms, notifications, timers, and safety indicators in both DIY and professional electronics projects.

This versatile buzzer works with a wide voltage range, making it compatible with Arduino, Raspberry Pi, ESP32, and other microcontrollers for various audio alert applications.
