Frequently asked questions
What is the price of Piezo Element 50mm Piezoelectric Knock & Vibration Sensor in Egypt?
Piezo Element 50mm Piezoelectric Knock & Vibration Sensor currently costs 30 EGP in Egypt.
Where can I buy Piezo Element 50mm Piezoelectric Knock & Vibration Sensor in Egypt?
Piezo Element 50mm Piezoelectric Knock & Vibration Sensor is available from Microohm. Compare the offers above to find the best price.
How do I connect it to an Arduino?
Connect the disc to an analog input with a high-value resistor, typically around 1 MΩ, from the input to ground. Because the output is a short high-impedance pulse, the resistor keeps the signal stable, and clamp diodes can protect the ADC pin.
Does it need a power supply?
No. It is a passive sensing element that generates its own voltage when deformed by a knock or vibration. The signal then needs conditioning in your circuit before reading it.
