Piezo Buzzer 20mm
The Piezo Vibration Sensor is a compact piezoelectric sensor designed to detect mechanical vibrations and knocks. When subjected to physical stress, such as tapping or knocking, the piezoelectric material generates a voltage signal proportional to the force applied. This makes it ideal for applications requiring impact detection, vibration monitoring, or as a simple input device in interactive projects.
Additionally, when an AC voltage is applied, the element can function as a buzzer, producing audible tones. Its dual functionality allows for both sensing and sound generation, making it a versatile component in electronic designs.
Features :
- Detects mechanical vibrations and knocks through the piezoelectric effect.
- Generates voltage signals proportional to applied force.
- Can function as a buzzer when driven with an AC voltage.
- Compact and lightweight design for easy integration.
- Suitable for both sensing and sound-generating applications.
- Pre-soldered leads.

Handling & Safety
Always confirm the rating, polarity and pinout of a buzzer before installing it, and avoid exceeding its rated voltage or current. Use proper ESD precautions with sensitive parts. These steps protect your circuit and keep your work safe.
Why Choose This Buzzer
First, it is a widely used part in electronics repair, prototyping and assembly, so it fits into most existing projects easily. Second, the value, rating or pin count is clearly stated, so you can match it to your circuit with confidence. Third, our team checks basic function before it ships. So, you avoid guesswork when you order. As a result, this is a dependable choice for repair, prototyping or a finished project.
Usage Tips
Before soldering or installing, match the value, package and pin layout with your circuit diagram. Therefore, you avoid a wrong fit or a damaged board. Also, keep small parts stored in labeled bags so values do not get mixed up during a project. As a result, your build stays organized and easier to troubleshoot.
Good to Know
A well-matched buzzer saves time on the job later. Therefore, double-check the value, rating and pin layout against your circuit before relying on it in a final build. Also, keep the original packaging until you have tested the part, since this makes any exchange easier if something is not right. As a result, your project stays reliable with fewer surprises.
البازر الكهروضغطي (Piezo Buzzer)
يُعد مستشعر الاهتزاز الكهروضغطي (Piezo Vibration Sensor) جهازًا مدمجًا مصممًا لاكتشاف الاهتزازات والطرق الميكانيكية. عند تعرضه لإجهاد ميكانيكي مثل النقر أو الطرق، ينتج العنصر الكهروضغطي إشارة جهد تتناسب مع القوة المطبقة. وهذا يجعله مثاليًا للتطبيقات التي تتطلب اكتشاف الصدمات أو مراقبة الاهتزازات أو استخدامه كجهاز إدخال بسيط في المشاريع التفاعلية.
بالإضافة إلى ذلك، عند تطبيق جهد متردد (AC)، يمكن للعنصر أن يعمل كـ بزر (Buzzer) ينتج أصواتًا مسموعة. وتمنحه هذه الوظيفة المزدوجة القدرة على الاستشعار وإنتاج الصوت في الوقت نفسه، مما يجعله مكونًا متعدد الاستخدامات في التصميمات الإلكترونية.
الميزات:
-
يكتشف الاهتزازات والطرق الميكانيكية من خلال التأثير الكهروضغطي.
-
