5V Active Buzzer – Loud Beep Alarm Module

5V Active Buzzer Alarm Module – High Decibel Sound Beeper

Product Overview

The 5V Active Buzzer Alarm Module is an essential sound-generating component widely used in security systems, alert circuits, and embedded electronics. It operates by producing a loud and clear beep sound when powered, making it ideal for various notification and alarm applications. Unlike passive buzzers, this active buzzer generates sound without needing an external oscillating signal, simplifying integration with Arduino, Raspberry Pi, and other microcontrollers.

With a sound pressure level of 82dB, this buzzer ensures high audibility even in noisy environments. Its compact size and through-hole mounting make it easy to install in circuit boards. Operating within a voltage range of 2V to 5V DC, it is suitable for both low-power and high-performance projects.

User Guide / How to Use

Using the 5V Active Buzzer in a project is straightforward. Follow these steps:

1. Connect Power: Attach the positive (+) pin of the buzzer to the 5V or 3.3V output of your microcontroller.
2. Ground Connection: Connect the negative (-) pin to the ground (GND).
3. Microcontroller Control (Optional): If controlling with an Arduino or Raspberry Pi, connect the signal pin to a digital output pin.
4. Programming (Optional): Use a simple code snippet to turn the buzzer ON and OFF at desired intervals.

Here’s a basic Arduino code to control the buzzer:

void setup() {
  pinMode(8, OUTPUT); // Set Pin 8 as Output
}

void loop() {
  digitalWrite(8, HIGH); // Turn ON the buzzer
  delay(1000); // Wait for 1 second
  digitalWrite(8, LOW); // Turn OFF the buzzer
  delay(1000); // Wait for 1 second
}
