The MEAS Vibration sensor is flexible and durable.
The Phidget Vibration Sensor is a piezo deflection sensor for the Phidget 8/8/8.
This low-cost project uses an 8 pin microcontroller to create an electronic pet with LED eyes and a piezo sounder voice that reacts to touch (via a push switch) and light (via a miniature LDR).
Small electret microphone. Useful in acoustic and audio applications, voice recordings.
