Vibration Detector vs Frequency Analyzer

The Vibration Detector utilizes the device’s accelerometer to measure and record vibrations or seismic activity. It can function as a vibration meter, seismograph, or seismometer. Using MEMS sensor technology, the app captures real-time vibration data across three axes (X, Y, Z) and applies sensor fusion to remove gravitational components for accurate measurements. Core Functionality • Timestamped vibration recording • Configurable logging and alert thresholds • Audible alerts on threshold exceedance • Battery-efficient dim mode • Lightweight implementation Measurement & Units Supports multiple units including G-force (g), in/s, and mm/s with instant conversion. Dual Threshold System Separate thresholds allow independent control of data logging and alert triggering. Data Logging Events are stored with timestamps and can be managed or cleared easily. Stealth Mode Fully disables screen output for long-term monitoring while maintaining data collection. UI Design Bottom-aligned controls ensure unobstructed data visualization. Workflow Mount device → Configure thresholds → Start monitoring → Analyze logged data
