Add reliable audible feedback to your projects with the Electronics Series. This 22mm Piezoelectric Buzzer is a versatile signaling device that operates across a wide voltage range (3V to 12V). It is the definitive solution for alarm systems, DIY electronics, and industrial status indicators that require a clear, consistent "beep" or "tone."
Wide Voltage Compatibility: Works seamlessly with 3V, 5V (Arduino/TTL), 9V, and 12V (Automotive/Security) power sources.
Pre-Wired for Convenience: Comes with 10cm–15cm red and black tinned leads, allowing for quick soldering or connection to terminal blocks without needing special tools.
High Sound Pressure Level (SPL): Despite its compact 22mm size, it produces a sharp, piercing tone (typically 80dB+) that can be heard clearly in noisy environments.
Arduino & Robotics: Use as a status indicator for "power on," "low battery," or "sensor triggered" alerts.
Home Security: Integrate into door/window sensors or DIY alarm panels for entry chimes or warning sirens.
Automotive Alerts: Perfect for custom reverse sensors, turn signal "clickers," or headlight-on reminders.
Industrial Panels: Add an audible dimension to control panels to alert operators of system errors or cycle completions.
Constant Tone: Once power is applied, it emits a continuous high-frequency beep. (Can be pulsed via software for different alert patterns).
Simple Polarity: Red wire connects to Positive (+), Black wire connects to Ground/Negative (-).
Easy Mounting: The 22mm diameter housing often includes mounting "ears" or can be easily secured with double-sided adhesive or hot glue.
Lightweight Design: Encased in a durable, flame-retardant ABS plastic shell that adds minimal weight to portable devices.
Product Type: Electronic Piezo Buzzer
Operating Voltage: DC 3V – 12V
Diameter: 22mm
Included: 1x 22mm Wired Buzzer
1. Can I plug this directly into an Arduino pin? Yes! Because it draws very little current (under 20mA), you can drive it directly from a digital I/O pin on an Arduino or Raspberry Pi.
2. Is the tone adjustable? Not via voltage. The "pitch" is fixed by the physical piezo element. However, you can change the volume by varying the voltage (3V is quieter, 12V is louder).
3. Is it waterproof? The ABS casing is splash-resistant, but the sound hole at the top and the wire exit point are not sealed.
