- Wide operating voltage: Can operate from approximately 3V to 7V.
- Low current consumption: Draws up to approximately 30 mA under rated conditions.
- High sound output: Produces more than 82 dB at a distance of 10 cm.
- Continuous tone: Provides a steady audible sound when energized.
- Compact DIP package: Suitable for breadboard prototyping and PCB mounting.
- Easy microcontroller control: Can be switched directly using a suitable digital output or transistor driver.
- Wide operating temperature range: Suitable for applications operating from -20°C to 45°C.
Principle of Operation
The 5V DIP Active Buzzer contains an internal oscillator and sound-generating element. When a DC voltage is applied across its terminals within the specified operating range, the internal oscillator generates an electrical signal that drives the sound-producing element, resulting in a continuous audible tone.
Because the oscillator is built into the buzzer, a microcontroller does not need to generate the tone frequency itself. For example, an Arduino can turn the buzzer ON by setting a digital output HIGH and turn it OFF by setting the output LOW, provided the buzzer's current requirements are within the safe output limits of the selected GPIO pin.
Applications
- Alarm and warning systems
- Door and security alerts
- Motion detection systems
- Timer and reminder notifications
- Arduino and microcontroller projects
- Interactive electronic displays
- Control panels and user-interface feedback
- Game and educational projects
- Embedded system status indicators
- General-purpose audible notifications
Pinout
The buzzer is a two-terminal component. Polarity markings on the buzzer body normally identify the terminals.
| Pin | Connection | Function |
|---|---|---|
| + | VCC / Positive Supply | Positive power input |
| - | GND | Ground / negative connection |
Wiring
The buzzer can be connected directly to a suitable 5V supply or controlled by a microcontroller. For simple low-current applications, connect the positive terminal to a suitable digital output and the negative terminal to GND.
| Buzzer | Arduino | Function |
|---|---|---|
| + | Digital Pin | ON/OFF control |
| - | GND | Ground |
Note: Although the buzzer is rated up to approximately 30 mA, avoid exceeding the recommended current rating of the microcontroller's GPIO pin. For higher current applications or when driving the buzzer from a higher-voltage supply, use a suitable transistor or MOSFET driver.
