Metal Detector - track value

- Metal Detector app is simple to use, just open it and move it around. If the magnetic field values rise there is metal in the area.
- How Metal Detector works?
• This app uses the built-in magnetic field sensor of your smart phone.
• First of all after running this app if your phone shows high reading then immediately keep it away from everything to set it normal (0μT – 59μT).
• The normal Electromotive force (EMF) field level is about 59μT (micro Tesla) or 590mG (milli gauss); 1μT = 10mG. When any metal object like steel or iron is near, EMF reading will increase with a beef sound.
