Description

Super Loud 5V Active Alarm Buzzer Beeper

The Super Loud 5V Active Alarm Buzzer Beeper is a small electronic sound indicator used to generate audible alerts in electronic circuits and embedded systems. Unlike a passive buzzer, an active buzzer contains an internal oscillator that produces a fixed-frequency tone when DC power is applied.

This makes it easy to integrate into microcontroller-based projects because it can be controlled using a simple ON/OFF signal. It is suitable for Arduino boards, alarm circuits, sensor-based warning systems, robotics projects, and other applications that require an audible notification.

With a typical sound output of approximately 85dB at 10cm on commonly listed versions, it can provide a noticeable warning tone in compact electronic devices.

Technical Specifications

Specifications are based on commonly listed versions of this buzzer. Confirm the physical dimensions and electrical ratings of the supplied batch before installation.

Key Features

• 5V DC operation: Designed for common 5V electronic and microcontroller projects.

• Loud audible output: Produces approximately 85dB sound output at 10cm on specified versions.

• Built-in oscillator: Generates its own tone without requiring an external oscillator circuit.

• Simple ON/OFF control: Can be activated through a suitable digital control signal.

• Compact design: Requires very little space on electronic boards and DIY projects.

• Quick response: Produces an audible tone when powered.

• Wide compatibility: Suitable for compatible Arduino, sensor, alarm, and robotics circuits.

Applications

• Arduino and microcontroller projects.

• Security and warning alarm systems.

• Obstacle-detection robots.

• Blind-stick alert systems.

• Fire and gas detection alarms.

• Water-level monitoring systems.

• Electronic doorbells and notification circuits.

• Industrial status indicators.

• DIY electronics and STEM projects.

How to Use

1. Identify the positive (+) and negative (−) terminals.

2. Connect the positive terminal to a suitable 5V DC supply.

3. Connect the negative terminal to GND.

4. Apply the correct DC voltage to activate the buzzer.

5. To control it using Arduino, use a suitable digital output or transistor driver circuit.

6. Switch the control signal OFF to stop the sound.

Arduino example:

const int buzzerPin = 8;

void setup() {
  pinMode(buzzerPin, OUTPUT);
}

void loop() {
  digitalWrite(buzzerPin, HIGH);
  delay(1000);

  digitalWrite(buzzerPin, LOW);
  delay(1000);
}

This example produces one second of sound followed by one second of silence. The logic level required depends on the buzzer’s particular connection and circuit design.

Precautions

• Use the recommended 5V DC supply.

• Do not exceed the specified operating voltage.

• Observe terminal polarity when connecting the buzzer.

• Check the current requirements before connecting directly to a microcontroller pin.

• Use a transistor driver if the buzzer current exceeds the GPIO pin’s safe output capability.

• Avoid prolonged exposure to loud buzzer sounds near the ears.

• Keep the component away from moisture and excessive heat.
