metal detector or metalSniffer
Metal Detector / metal sniffer app that detects the presence of metal by Using your phone.
This app measures magnetic field with an embedded magnetic sensor.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, magnetic field level will increase. larger the metal object the stronger the magnetic field and the green trace will move lower down the screen. You will also hear a change in pitch sound, the higher the pitch the larger the metal object.
Metal Detector / metal sniffer app detecting nearby electromagnetic fields using the phone's built-in magnetometer/compass, you can locate nearby metal and magnets.
Very simple, just move the app around and read the measurements, if the magnetic field readings go over a critical level, the phone will vibrate, meaning a ferromagnetic material is nearby.
A must handy tool for security reasons. Detects knife, pistols and other dangerous weapons in side the human body.Take a full body scan through body metal detector and find the items based on metal and irons that are prohibits by governments.
If the app does not work as it should then the problem is in your magnetic sensor. Maybe your device does not have one. Or try to initialize the sensors by pointing your phone up and rotate it in a figure 8 pattern. Remove magnetic covers from your device for accurate readings. Magnetic covers will influence the magnetic sensor in your Android device. If your device's case contains metal elements remove the case before using the app.
