Metal Detector Specifications
|
Find metal and electromagnetic waves with your device.
Metal Detector is in the 3rd set of the Smart Tools collection.
<< Metal Detector apps require a magnetic sensor (magnetometer). If this app does not work properly, please check the specifications of your device. >>
This app measures magnetic field with an embedded magnetic sensor.
The magnetic field level (EMF) in nature is about 49T(micro tesla) or 490mG(milli gauss); 1T = 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.
