  • A 5V Active Alarm Buzzer Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric.
  • VCC external 3.3V~5V voltage (can be directly connected to the 5V microcontroller and 3.3V microcontroller)
  • Programmable, easy to control- SCM can let a high-low sound- while passive buzzer did not.

Active Buzzer Module

An Active Buzzer Alarm Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. Just like what you are viewing now, it is a 3.3V-5V DC Electronic Part Active Buzzer Module. Using top-quality material, it is durable in use. 

An 5V active buzzer rings out as long as it is electrified. Compared with a passive buzzer, it is a bit expensive but easier to control. Typical uses of buzzers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.
Module Interface Specification (3-wire)
+ External 3.3V-5V voltage (can be directly connected with the 5v and 3.3v MCU MCU)
– External GND out external microcontroller IO port


  • The 5V buzzer can be used in making Fire Alarm using Arduino

1. What is the Active buzzer module?

  • When the signal level is high, the Active Buzzer module emits a single-tone sound. Use the Passive Buzzer module to create various tones. A piezoelectric buzzer with an integrated oscillator makes up the Active Buzzer module. It generates a sound of approximately 2.5 kHz when the signal is high.

2. How does the buzzer module work?

  • It's simple, tone(buzzer, 1000) sends a 1KHz sound signal to pin 9, delay(1000) pauses the program for one second and noTone(buzzer) stops the signal sound. The loop() routine will repeat this process, emitting a short beeping sound each time.

3. How do I connect the active buzzer module to Arduino?

  • The Connections are pretty simple: Connect the Supply wire (RED) of the buzzer to the Digital Pin 9 of the Arduino through a 100-ohm resistor. Connect the Ground wire (BLACK) of the buzzer to any Ground Pin on the Arduino. That's all of it.

4. What is the difference between a passive and an active buzzer?

  • An active buzzer generates the sound itself. You basically just turn it on or off. A passive buzzer needs a signal source that provides the sound signal. You can tell which is which by measuring the resistance between the two leads.
