DFRobot Gravity Flexible Piezo Film Vibration Sensor - PH2.0 3-Pin Interface
The DFRobot Gravity Flexible Piezo Film Vibration Sensor is an Arduino-compatible module designed for detecting vibrations, impacts, and touch. It features a flexible PVDF piezoelectric film and a converter board with both digital and analog outputs, interfacing via the standard Gravity PH2.0 3-pin connector for easy integration with microcontrollers like Arduino, ESP32, and Raspberry Pi.
Features
- Flexible PVDF piezoelectric film sensor for detecting vibration, impact, and touch.
- Provides both digital (switch) and analog (intensity) output signals for versatile interfacing.
- On-board potentiometer for adjusting output sensitivity and trigger threshold.
- Standard Gravity PH2.0 3-pin interface for plug-and-play compatibility with DFRobot and Arduino shields.
- Wide dynamic range suitable for applications from subtle vibrations to high-impact shocks.

This sensor module utilizes a flexible 28 µm thick piezoelectric PVDF polymer film laminated to a polyester substrate. When bent or deformed, the film generates a high voltage signal proportional to the applied strain, enabling it to act as a sensitive vibration detector or a flexible switch. The integrated converter board conditions this signal, providing both a digital logic output for threshold-based detection and an analog output for measuring vibration intensity.
Designed for durability, the sensor operates from 0°C to 85°C and can withstand significant mechanical deflection. The on-board sensitivity adjustment allows fine-tuning for specific applications, from detecting minute vibrations to registering strong shocks. Its universal Gravity interface simplifies wiring, making it an ideal component for prototyping and embedded systems requiring reliable vibration sensing.
