5V Active Buzzer Module – Loud Alarm Sound for Arduino & Electronics

This 5V Active Buzzer is a small sound module that produces a continuous tone when connected to power. It’s ideal for use in Arduino projects, home security systems, robotics, and any application that requires sound alerts or notifications.

Unlike passive buzzers, this active buzzer has an internal oscillating circuit, which means it doesn’t require PWM signal—just connect to 5V and GND to sound.

Perfect for students, DIYers, and embedded developers in Bangladesh looking for reliable sound modules.
