Active Buzzer Module

The Active Buzzer Module is a compact electronic sound module designed to generate an audible tone when powered. Unlike a passive buzzer, the active buzzer has a built-in oscillator, so it can produce a continuous beep without requiring an external frequency signal. It features a simple 3-pin interface (S, +, -) and can be easily connected to Arduino, ESP32, Raspberry Pi, and other microcontroller boards. Features Built-in oscillator for easy sound generation Produces a continuous audible tone when powered Simple 3-pin interface: S, +, - Compact and lightweight design Easy to connect and use Suitable for Arduino, ESP32, Raspberry Pi and DIY projects Low-power electronic buzzer module Applications Alarm and warning systems Electronic doorbells Arduino and microcontroller projects Timer and notification systems Security alert systems Robotics projects Smart home automation DIY electronics projects Package Includes 1 × Active Buzzer Module
