Piezo Vibration Sensor (Large with Mass)

Overview

Unlock the power of mechanical motion with the MOKWN Piezo Vibration Sensor (Large with Mass). This robust sensor converts physical vibrations, shocks, and pressure into measurable electrical signals, making it an essential tool for any maker, engineer, or student. The integrated mass amplifies the signal, providing high sensitivity to even subtle movements. Whether you're building a smart alarm system, a musical instrument, or a robotics project, this sensor offers a reliable and direct way to interface with the physical world.

Key Features

• High Sensitivity: The attached mass increases the sensor's response to vibrations and impacts, ensuring accurate detection.
• Wide Detection Range: Capable of sensing everything from gentle taps to strong shocks and continuous vibration.
• Durable Construction: Built to withstand repeated use in various environments, perfect for prototyping and permanent installations.
• Easy to Interface: Simple two-wire connection, compatible with most microcontrollers like Arduino, ESP32, and Raspberry Pi.
• Versatile Functionality: Works as a vibration sensor, impact sensor, flex sensor, and even a simple sound pick-up.
