Metal Detector

Find the metal and electromagnetic waves with your phone.
Metal Detector is in the 3rd set of the Smart Tools collection.
This app measures magnetic field values using the magnetic sensors that is built into the phone. The magnetic field level(EMF) in nature is about 49µT(microtesla) or 490mG(milligauss); 1µT = 10mG.
If there is any metal in the area, the strength of the magnetic field should increase. Among other uses, it can be helpful in finding electrical wires in walls and metal in the ground.

Usage is simple: Open this app on your device, and move it around; The magnetic field values will constantly fluctuate; See the YouTube video for a demonstration. That’s it!
The accuracy depends entirely on the sensors in your device. Note that the magnetic sensor is affected by electronic equipment (TVs, PCs, etc.) due to electromagnetic waves. This is not a bug in the app.
If this app does not work properly, it may mean that your phone’s sensors are damaged, broken or non-existent. To initialize the sensors, point your phone up towards the sky and move it in a figure 8 pattern.
Sometimes a leather case with a magnetic “snap” can cause unwanted results. Remove the case to increase accuracy.
