Metal Detector

Turn your Android device into a utility tool with Metal Detector, a clean and responsive application designed to measure magnetic fields and help you find ferromagnetic objects around you.

By utilizing your smartphone’s built-in magnetic sensor (magnetometer), this application tracks environmental magnetic fluctuations in real time and displays them through a highly visible, premium digital interface.

## 🚀 Key Features

* Real-Time Magnetic Gauge: A beautifully crafted digital dashboard featuring a responsive needle that reacts instantly to changes in the surrounding magnetic field.
* Signal Strength Indicator: Easily monitor magnetic field intensity levels to pinpoint the exact location of nearby magnetic materials.
* Sleek Premium UI: Designed with a high-contrast dark theme, custom carbon-fiber patterns, and neon accents for optimal visibility in any lighting condition.
* Completely Local Processing: All sensor data is processed directly on your device, ensuring maximum privacy and instant feedback.

## 🛠️ How It Works

The app measures the magnetic field value using the embedded magnetic sensor inside your mobile device. In nature, the standard magnetic field level (EMF) is about 49μT (microteslas) or 490mG (milligauss). When any ferromagnetic metal (such as iron, steel, or nickel) is close to your phone, the intensity of the magnetic field will increase, causing the gauge needle to rise.

## ⚠️ Important Hardware Notice (Please Read)

To ensure 100% transparency and a proper user experience, please review the following requirements:
1. Magnetometer Required: This application requires a built-in magnetic sensor (magnetometer) to function. If your specific mobile device does not possess this internal hardware component, the application will display a clear notification and will not be able to measure fields.
2. Detection Limitations: This app measures changes in magnetic fields caused by ferromagnetic materials (iron, steel, etc.). It cannot directly detect non-magnetic metals like pure gold, silver, or aluminum coins on its own, as they do not affect the earth's static magnetic field.
3. Interference: Electromagnetic waves from nearby electronic devices (like computer monitors, TVs, or heavy power bricks) and magnetic components in phone cases can affect sensor accuracy.
