PZT-Sim Vibration Sensing Module

Description

The PZT-Sim Vibration Sensing Module is a compact analog sensor board built around a piezoelectric ceramic disc. Unlike digital vibration switches that only provide a simple HIGH/LOW signal, this module uses the piezoelectric effect to generate an electrical signal proportional to the strength of mechanical vibration, impact, or shock .

When the ceramic disc is deformed by vibration, it produces a small voltage that is buffered by the onboard circuitry and output as an analog signal. This allows a microcontroller’s ADC to read a value that increases with vibration intensity, enabling applications such as electronic drum triggers (where hitting harder produces a larger signal) and impact monitoring (where the severity of a shock can be assessed) .

The module operates from 3.3V or 5V with very low current consumption (<1mA), making it suitable for battery-powered and embedded projects. It connects via a simple 3-pin interface: S (Signal), + (VCC), and – (GND) . The compact PCB measures approximately 30mm × 23mm with a 27mm diameter ceramic disc .

Critical limitations: The output is not calibrated—it provides relative vibration intensity, not absolute acceleration or displacement measurements. The sensor is not waterproof and is not suitable for high-temperature environments (operating range typically -10°C to +70°C) . For precise vibration analysis or frequency-domain measurements, a proper accelerometer with digital output is more appropriate.
