5V Active Buzzer Black

5V Active Buzzer Module – Sound Alarm Module for Arduino and Embedded Projects

The 5V Active Buzzer Module is a compact and easy-to-use sound-generating device designed for use in embedded systems, DIY electronics, and Arduino projects. Unlike a passive buzzer, this active buzzer includes an internal oscillating circuit, allowing it to produce a continuous tone when powered – no need for PWM or external frequency generation.

Simply apply 5V DC to the module, and it emits a clear audible tone, ideal for alarms, timers, notifications, and alert systems in electronics projects. It features a standard 3-pin interface (VCC, GND, Signal), making it compatible with Arduino, ESP32, STM32, and other microcontrollers.
