Piezo Element Detect Vibration 35mm

From the shop's description

Piezo Element Detect Vibration 35mm is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. 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. Resonant Frequency(kHz): 6.3 ±0.6kHz Resonant Impedance (ohm): 1000 max Capacitance (nF): 10.0 ±30% [1kHz] To use it with your Arduino Board “ Project “ It’s perfect for DIY makers, students, and anyone building custom electronic circuits or STEM kits.
