Metal detector application requires a magnetic sensor (magnetometer). If this application does not work properly, please check the phone specifications.
A metal detector is a tool for searching for metals using an integrated magnetic sensor. The magnetic field level (EMF) in nature is about 49μT (micro tesla) or 490 mg (mGS); 1μT = 10mg. The presence of metals in the sensitivity range of the sensor can increase this value. Among other things, it can be useful in finding electrical wires in walls and metal in the ground.
It is very easy to use metal detector, you just need to launch this application on your mobile device and move it around. You will see that the level of the magnetic field displayed on the screen is constantly changing. The colorful lines represent three dimensions, and the numbers on top show the value of the magnetic field level (EMF). That’s all.
Accuracy of the sweeper depends entirely on the type of your mobile device. The magnetic sensor responds to electronic devices (televisions, computers), because they emit electromagnetic waves. Please do not blame this application.
The metal detector cannot detect gold, silver or coins made from copper. They are classified as non-ferrous metals that do not have a magnetic field.
