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.
