ELF magnetic field detector using your phone’s magnetometer sensor
ELF Detector – Extremely Low Frequency Magnetic Field Analyzer
ELF Detector is a professional tool designed to measure and analyze Extremely Low Frequency (ELF) magnetic fields using your Android device’s built-in magnetometer sensor.
It detects real-time changes in the magnetic field for researchers, students, and anyone interested in studying natural and artificial electromagnetic sources.
⚡ Key Features
Real-time Magnetic Field Detection
Measure and monitor magnetic field strength in microtesla (µT) across ELF frequency ranges.
ELF Frequency Analysis
Detect Extremely Low Frequency (0.1 Hz – 100 Hz) magnetic variations generated by natural or man-made sources.
Adjustable Sensitivity Threshold
Set your own detection threshold to focus on weak signals or reduce background noise.
Sensor-Based Precision
Uses your device’s magnetometer for direct magnetic field measurement—no internet or GPS required.
Scientific and Educational Use
Perfect for geophysical monitoring, electromagnetic studies, and classroom demonstrations on ELF phenomena.
What Are ELF Magnetic Fields?
ELF (Extremely Low Frequency) magnetic fields range from 1 Hz to 100 Hz.
They are produced naturally by the Earth and lightning (such as Schumann resonances) and artificially by electrical devices and power lines.
Measuring ELF magnetic fields can help understand environmental EM activity, energy transmission, and electromagnetic safety.
How to Use
Open ELF Detector and hold your device steady.
Observe real-time magnetic field readings in microtesla (µT).
Adjust the threshold to highlight significant field changes.
Use readings for experiments, research, or environmental monitoring.
⚙️ Technical Notes
Accuracy depends on your phone’s magnetometer quality.
Avoid metal objects or strong magnets near your device during use.
Applications
ELF field detection
Environmental and geophysical monitoring
Scientific and classroom research
Studying electromagnetic interference or exposure levels
🔒 Privacy
ELF Detector respects your privacy.
No personal data is collected, stored, or shared. All measurements remain on your device.
Discover the invisible world of ELF magnetic energy around you.
Measure. Detect. Explore.
