About Magnetometer: Metal Detector

Magnetometer with live field readings, proximity alerts, and compass heading.

Magnetometer is a real‑time magnetic field viewer for Android. It shows live µT readings, heading, and a history graph so you can see how the magnetic field changes as you move your device.

Key features:

- Live magnetic field strength (µT) and 3‑axis values (X/Y/Z)

- Compass heading with tilt compensation

- Proximity indicator (COLD / WARM / HOT)

- Adjustable sensitivity (detection threshold)

- Sound and vibration alerts that intensify with stronger signals

- Calibration to set a baseline for accurate detection

- History graph to visualize changes over time

- Demo mode for testing on devices without a magnetometer

Notes:

- This app is for fun/experiments and does not replace professional metal detectors.

- Only magnetic (ferromagnetic) materials significantly affect the readings.
