Working Principle The connected vibration sensor converts tiny mechanical movement caused by heartbeat into weak analog voltage signal. Signal enters low-noise amplifier circuit for gain adjustment. Multi-stage filter removes environmental vibration and electromagnetic noise. Analog signal converts to digital value by high resolution ADC. Onboard processor preprocesses raw signal and outputs BCG waveform data to host unit through communication port.
Installation Requirements Install module on low-vibration fixed base; Route sensor cable with full shielding; Isolate module from heavy mechanical vibration sources; Provide clean DC power supply; Shield grounding must be properly connected.
Precautions for Use Avoid strong mechanical shock on sensor and module; Prevent large external vibration from saturating signal input; Keep module surface dry; Check sensor connection tightness regularly; Do not operate near large rotating machinery.
