20mm Piezo Transducer - 10Pcs

Package Include: 10pcs 20mm Piezo Transducer

Piezo elements come in handy when you need to detect vibration or a knock. You can use these for tap or knock sensors pretty easily by reading the voltage on the output. They can also be used for a very small audio transducer such as a buzzer.
