Metal Detector

 Metal Detector applications require a magnetic sensor (magnetometer). If this application does not work properly, check your specifications, please.
 
This application measures the magnetic field using a magnetic sensor that is built into your device.
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, the magnetic field level will increase.

The use is very simple: launch this application on your mobile device and move it. You will see that the magnetic field level shown on the screen fluctuates constantly. Colored lines represent the three dimensions and the numbers on the top shows the value of the magnetic field level (EMF). The table will increase and the device vibrates and makes sounds announcing that the metal is near. In the settings, you can change the sensitivity of vibration and sound effects.

Warning! Not all smartphone models has a magnetic field sensor. If your device does not have it, the application will not work.
