Metal Detector is in the 3rd set of the Smart Tools collection.
>
This app measures magnetic field with an embedded magnetic sensor.
The magnetic field level (EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG. When any metal(steel, iron) is near, magnetic field level will increase.
Usage is simple: Open the app, and move it around. The magnetic field level will constantly fluctuate. That's it!
You can find electrical wires in the walls (like a stud detector) and iron pipes in the ground.
A lot of ghost hunters had downloaded this app, and they had experimented as a ghost detector.
The accuracy depends entirely on your magnetic sensor (magnetometer). Note that it is affected by electronic equipment (TV, PC, microwave) due to electromagnetic waves.
