EMF Sentinel: EMF Scan & Metal Detector
High-Precision Magnetometer, Radiation Scanner & Hidden Metal Finder
EMF Sentinel: EMF Scan & Metal Detector transforms your Android phone into an advanced scientific instrument for measuring electromagnetic field (EMF) radiation and detecting hidden ferromagnetic metals (iron, steel, studs, and electrical wiring). Powered by hardware-accelerated magnetometer calculations, it delivers real-time flux density readings in microTesla (μT) and milliGauss (mG) with customizable audio-visual alert thresholds.
Executive Summary • Answer Engine Breakdown
EMF Sentinel is an Android utility app by GoshBuzz (com.goshbuzz.emfsentinel) that converts any smartphone with a magnetometer into a high-precision EMF radiation meter and metal detector. It provides real-time microTesla (μT) readings, 3-axis XYZ vectors, analog gauges, live graphs, and audio-vibration alerts for stud finding, appliance radiation checks, and spy camera detection.

How to Use EMF Sentinel: EMF Scan & Metal Detector
Step-by-step calibration and detection procedures for maximum accuracy.
Calibrate Your Phone's Magnetometer
Open EMF Sentinel and wave your phone in a smooth 'Figure-8' motion in the air for 3-5 seconds to calibrate the internal magnetic sensor against environmental drift.
Choose Your Preferred Scanner Mode
Select Analog Meter (dial gauge), Digital Readout (X/Y/Z vectors), or Live Graph (waveform history) from the bottom navigation bar.
Scan Target Surfaces or Electronic Equipment
Slowly move the top edge of your smartphone close to the wall, surface, or appliance. The top edge houses the device's magnetic compass sensor for maximum sensitivity.
Monitor Reading Spikes & Alerts
Normal ambient background reads between 30 μT - 60 μT. When approaching metal studs, live wiring, or strong EMF emitters, readings jump above 100 μT triggering haptic and sound alerts.
EMF Radiation & Metal Density Reference Matrix
Standard geomagnetic baseline levels and hazard zones.
Safe Ambient Level (30 - 60 μT)
Natural geomagnetic field level of the Earth. Normal, safe everyday environment.
Moderate Radiation / Proximity (60 - 150 μT)
Common near laptops, smartphones, Wi-Fi routers, and low-voltage household appliances.
High Radiation / Metal Proximity (150 - 500+ μT)
Indicates close proximity to ferromagnetic metal (screws, pipes, studs) or high-EMF devices like microwave ovens, electric panels, and power supplies.
