Magnetic Sensor

Measure EMF radiation & magnetic fields with magnetometer and offline compass

Measure magnetic fields accurately and navigate with confidence—this multifunctional sensor toolkit turns your device’s built-in magnetometer into a precise EMF/magnetic field meter and a reliable offline compass. Designed for research, DIY projects, and outdoor use, it delivers clear, real-time readings and practical tools without gimmicks.

Core features

• EMF/Magnetic Field Meter (Gauss Meter): View 3 axis (X/Y/Z) magnetometer data in microtesla (µT) with real time updates to assess magnetic field strength around you.

• Compass Sensor (Offline): Use a dependable, on device compass for navigation without mobile data or Wi Fi—ideal for hiking, camping, and fieldwork.

• Real-Time Analysis: Monitor live magnetic field values and vector changes to help pinpoint areas of elevated field strength.

• Alerts & Thresholds: Set custom µT limits and receive notifications when the magnetic field exceeds your chosen threshold.

• Data Logger: Record magnetic field readings over time and review detailed logs directly in the app for experiments or diagnostics.

• Sensor Diagnostics: Check the presence and status of key sensors (magnetometer, accelerometer, gyroscope) on your device.

What you can do

• Check magnetic field levels near electronics, speakers, power supplies, or magnets.

• Run simple science experiments, classroom demos, and DIY measurements.

• Use the offline compass for basic orientation on trails or in remote areas.

Why it helps

• Accurate, on device measurements using your phone’s magnetometer sensor.

• Clear, actionable data (µT, 3 axis) for investigations and field checks.

• Practical tools in one place: magnetic field detector, gauss meter, compass, logging, and alerts.

Notes and compatibility

• Requires a device with a built in magnetometer for EMF/magnetic field measurements.

• Results depend on sensor quality, calibration, and nearby interference (metal objects, cases, magnets).

• Measures the magnetic component of EMF only. It does not measure electric fields, radiofrequency (RF) signals (e.g., Wi Fi, microwave ovens), or ionizing radiation, and it is not a medical or safety instrument.

Get precise magnetic field readings, log your data, and navigate offline—all in one clean, dependable sensor app.
