Piezo buzzers are used for making beeps, tones and alerts. This one is petite but loud! Drive it with 3-30V peak-to-peak square wave. To use, connect one pin to...

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.

This small (14mm diameter) piezo element is nicely enclosed so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means...

This large (30mm diameter) piezo element is nicely enclosed with mounting holes so you can attach easily. Piezo elements convert vibration to voltage or voltage...

The DFRobot Vibration Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change which is propotional with the strength of vibration.

Surface transducers give you the awesome power to turn almost any surface into a speaker...

This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.

This Piezo Alarm is a great option for when you need an audible alarm (or are just looking for a way to prank your friends). This alarm has 16 different output options...

Turn any surface/wall/table etc into a speaker with a surface transducer. This type of speaker does not have a moving cone like most speakers you've seen. Instead...

This is an Arduino compatible piezo film vibration sensor. It is made up of flexible piezo film and converter board. The sensor is able to detect vibration, flexibility...

The Minisense 100 from Measurement Specialties is a low-cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. Useful for detecting vibration and ‘tap’ inputs from a user. A small AC and large voltage (up to +/-90V) is created when the film moves back an forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.

This thin silvery ribbon is an interesting sensor. It's made of 2mm wide by 600mm long piezoelectric film sandwich. Piezo film can be used to detect motion or vibration - when shifted around or touched, it creates a small current pulse across the terminals. If a 1 Mega-ohm resistor is placed across the two terminals you will see the current converted into a voltage that can be read by an analog-to-digital converter (ADC).
