Active Buzzer Module
Generate clear audible alerts and tones effortlessly with this Active Buzzer Module. Unlike passive buzzers, this module features a built-in oscillator circuit, meaning it produces sound the moment you apply a DC voltage - no external frequency signal required. Ideal for alarms, timers, feedback indicators, and notification systems in Arduino, Raspberry Pi, and microcontroller projects. Available now at The Engineer Store, Bengaluru, with fast shipping, 7-day warranty on manufacturing defects, and dedicated technical support.
Specifications
| Module Type | Active Buzzer (Built-in Oscillator) |
| Operating Voltage | 3.3V - 5V DC |
| Output Sound | Continuous tone (~2.5 kHz fixed frequency) |
| Control Method | High/Low digital signal (active low or active high, varies by module) |
| Interface | 3-pin header (VCC, GND, Signal/I/O) |
| Onboard Components | Active piezoelectric buzzer, transistor driver circuit, indicator LED |
| Sound Level | ~85 dB at 10 cm (typical) |
| Current Consumption | ~20-30 mA |
| Mounting | PCB with mounting hole for easy installation |
| Dimensions | ~32 mm x 13 mm x 10 mm (compact form factor) |
| Compatibility | Arduino, Raspberry Pi, ESP32, ESP8266, STM32, PIC, 8051, and other 3.3V/5V logic MCUs |
| Origin | Original / Authentic |
| Warranty | 7-day warranty on manufacturing defects |
| Support | Email & WhatsApp 24/7 |
Key Features
- Built-in Oscillator: Simply apply voltage or a HIGH signal and the buzzer sounds immediately - no need to generate PWM or square wave signals from your microcontroller.
- Plug-and-Play Module: Onboard transistor driver circuit allows direct connection to microcontroller I/O pins without additional components.
- Wide Voltage Range: Works reliably with both 3.3V and 5V logic systems, making it compatible with virtually all popular development boards.
- Loud & Clear Output: Produces a sharp, audible ~2.5 kHz tone at approximately 85 dB - easily heard in noisy environments.
- Onboard LED Indicator: Visual confirmation of buzzer activation status for easy debugging during development.
- Low Power Consumption: Draws only 20-30 mA, suitable for battery-powered and portable projects.
- Compact & Mountable: Small PCB footprint with a mounting hole for secure installation in enclosures and project housings.
- Simple Digital Control: One GPIO pin is all you need - set HIGH to sound, LOW to silence (or vice versa depending on module variant).
How It Works
An active buzzer module contains a piezoelectric buzzer element with an integrated oscillating circuit. When DC voltage is applied to the VCC and GND pins, the internal oscillator drives the piezo element at a fixed frequency (typically ~2.5 kHz), producing a continuous audible tone. The onboard signal pin connects through a transistor switching circuit, allowing a microcontroller GPIO pin to turn the buzzer on and off digitally. Because the oscillation is generated internally, you only need to send a simple HIGH or LOW signal - no need to write tone-generation code or use PWM timers. This makes the active buzzer module significantly easier to use than passive buzzers for basic alert and notification applications.
