Magnetic Sensor | Magnetometer

Turn your phone into a magnetic field meter (EMF Detector & Gauss meter) and offline compass — no extra hardware needed. Using your device's built-in magnetometer, this app displays real-time Gauss meter readings, 3-axis (X/Y/Z) field data, and offline navigation, all in one clean toolkit. Designed for teachers, students, DIY enthusiasts, and outdoor adventurers.

🚀 Key Features

- Magnetic Field Meter (EMF Detector / Gauss Meter): Monitor magnetic field strength in real time using 3-axis (X/Y/Z) magnetometer data. Readings are shown in microtesla (µT) to help you spot magnetic interference or changes in field strength.

- Offline Digital Compass: A compass that works with no mobile data or Wi-Fi — useful for hiking, camping, and orienting yourself in remote locations.

- Custom Alerts & Thresholds: Set your own magnetic field limits and get a notification when a reading crosses your chosen threshold.

- Data Logger: Record sensor readings over time and review the logs inside the app — useful for science experiments, comparisons, and simple diagnostics.

- Live Sensor Analysis: Visualize vector (X/Y/Z) changes in real time and spot when magnetic strength rises.

- Sensor Diagnostics: Check whether your device's magnetometer, accelerometer, and gyroscope are present and reporting data.

💡 Practical Use Cases

- Home & DIY: Check magnetic field levels near speakers, power supplies, electronics, and magnets.

- Education & Science: A tool for classroom demonstrations, physics experiments, and projects that involve data logging.

- Outdoor Navigation: Use the offline compass to help stay oriented on trails where GPS or signal is weak.

⚠️ Compatibility & Important Notes

- Hardware Requirement: This app relies on your device's built-in magnetometer. If your phone doesn't have this sensor, magnetic measurement features will not function.

- Accuracy Factors: Readings depend on the quality and calibration of your device's sensor. Metal objects, thick cases, and nearby magnetic interference can affect results. This is a consumer tool, not a calibrated scientific or medical instrument.This app measures magnetic fields only. It does not detect ionizing radiation, radiofrequency (RF) signals (such as Wi-Fi or 5G), or electric fields.
