Active Piezo Buzzer 3V to 12V – Sound Alarm Module for Arduino

This Active Piezo Buzzer is a compact, low-power sound module designed to generate a continuous beeping sound when voltage is applied. Unlike passive buzzers, it has a built-in oscillator — no need for signal pulses! Just connect it to power (between 3V to 12V), and it produces a loud and clear tone instantly.

Key Features:

• 🔔 Type: Active Buzzer (self-driven)
• 🔋 Operating Voltage: 3V to 12V DC
• 🔉 Sound Output: 85 dB ±10 dB (at 10cm, 5V)
• 🔁 Operating Frequency: ~2.7 kHz
• 📐 Size: Approx. 12mm diameter x 9.5mm height
• ⚙️ Mounting: PCB mountable with two pins

Applications:

• 📢 Warning and alert systems
• 🔐 Intrusion or theft alarms
• 🔧 Fault or error indicators
• 📦 Industrial status indicators
• 🎮 Arduino and Raspberry Pi projects

How to Use:

1. Connect the long pin (positive) to VCC (3V–12V), and the short pin (negative) to GND.
2. No code or signal needed — it starts buzzing as soon as powered.
3. Use a transistor or relay if you want to control it with GPIO from a microcontroller.
