2025-04-15 00:00:00 App Introduction: The Metal Detector is a multifunctional tool app that integrates metal detection and noise detection. Leveraging advanced Hall sensor technology and intelligent algorithms, users can easily detect surrounding metal objects and environmental noise levels. The app also supports custom threshold settings, and it will alert users when detected values reach or exceed the set thresholds. In the future, we will continue to update the app with more practical measurement tools to meet users' diverse needs. Main Features: Metal Detection: Uses the device's magnetic sensor to detect surrounding metal objects. The app displays real-time magnetic field intensity and peak values in various directions, helping users control the detection direction. Noise Detection: Detects the noise level in the environment after the user grants microphone recording permissions. The app displays real-time noise levels in decibels.
