Metal Detector is the part 3. of Smart Tools series.

This app is a tool to measure magnetic field values using the magnetic sensor that is built into the phone. Magnetic field level(EMF) in nature is about 49μT(490mG, 1μT=10mG).

If there is any metal around it, the values can be increased. So it can be used to find electrical wires in the walls and the metal in the ground.

The usage is simple. Open this app on your device, and move it around. The values will be changed. That's all.

The accuracy depends on your device exactly. The magnetic sensor responds to electronic products (TV, PC) due to electromagnetic waves. Please don't blame this app.

To initialize the sensors, point your phone up towards the sky and move it in a figure 8 motion.

* Sometimes the leather case that has a magnetic button could occur errors. remove it.
