Metal Detector is an intuitive and reliable way to identify magnetic field changes near ferromagnetic metals. It provides meter visualization, adjustable thresholds, and sound/vibration linkage feedback to bring a good experience to learning, experimentation, and daily detection scenarios.
Key features:
- Real-time magnetic field visualization
- Meter view shows total magnetic field strength with μT/mG unit switching
- Line charts show the trend of magnetic field fluctuations, making it easy to observe changes
- Intelligent alarm feedback
- Custom threshold, which is triggered when the limit is exceeded
- Two sound modes: beep / continuous tone, dynamic mapping of frequency and intensity
- Vibration feedback can be switched on and off independently, and the intensity changes with the magnetic field
Suggestions for use
- Calibration and then measurement: rotate in a "figure 8" shape according to the guidance in an open environment without strong magnetic interference
- Stay away from interference sources: such as strong magnets, transformers, and high-power electrical appliances to reduce errors
- Equipment requirements: Magnetic sensor is required (some devices may not support or have limited effects)
Disclaimer
- This application is based on a magnetometer and is only sensitive to ferromagnetic metals and magnetic changes; Not all metals can be effectively detected
- Detection results are affected by equipment model, sensor accuracy, ambient magnetic field, and user operation
- Do not use this app as the sole basis for professional testing such as security/engineering .etc
