DFRobot Gravity Flexible Piezo Film Vibration Sensor Module

The DFRobot Gravity Flexible Piezo Film Vibration Sensor Module is a versatile, Arduino-compatible sensor designed to detect vibrations, impact, touch, and bending with high precision.

It features a flexible piezoelectric PVDF film with screen-printed Ag-ink electrodes and a polyester backing, making it highly sensitive and durable. When the film is flexed or tapped, it generates a high voltage (up to ±90V), making it suitable for triggering MOSFET or CMOS circuits directly.

This piezo vibration sensor module supports both analog and digital outputs and connects easily using the Gravity 3-pin interface. It includes an onboard potentiometer to fine-tune sensitivity, allowing it to detect everything from subtle movements to strong impacts.

With a wide dynamic range (0.001Hz–1000MHz), it’s perfect for various projects, including motion detection, touch sensing, and impact-triggered systems.
