Active Buzzer
A simple 5V active buzzer that generates a tone using its built-in oscillator. Just apply a DC voltage and it sounds — no additional signal generation or driver circuit required. Ideal for adding audible alerts, alarms, or feedback tones to Arduino and microcontroller projects.
Key Features
- Active Type – Built-in oscillator generates tone with DC voltage only
- 5V Operation – Connects directly to microcontroller I/O pins
- Compact Size – 12mm diameter × 9.5mm height
- Simple Wiring – Just power and ground, no signal generation needed
Specifications
- Type: Active (built-in oscillator)
- Operating Voltage: 5V DC
- Diameter: 12mm
- Height: 9.5mm
Tip: An active buzzer has a built-in oscillator and produces a fixed tone when powered. A passive buzzer requires an external signal (e.g. PWM) to generate sound, allowing you to control the frequency and play different tones.
Also Available
Ideal For
- Arduino and microcontroller alert systems
- Alarm and notification circuits
- Button press feedback
- Electronics learning projects
Package Contents
- 1× Active Buzzer (5V)
