The 5V Active Electromagnetic Buzzer is a compact sound-generating module designed for alarm systems, Arduino projects, robotics, and embedded applications. Unlike passive buzzers, this active buzzer contains a built-in oscillation circuit, allowing it to produce a loud audible tone simply by applying a 5V power supply.

Its low power consumption, compact size, and easy interfacing make it ideal for warning indicators, notification systems, security devices, timers, and DIY electronics projects.
