Metal Detector - Magnetometer EMF - measure magnetic field value using a magnetic sensor that is built into your smartphone.
Now You can easily find metallic objects that are hidden underground, behind walls etc. , or be a treasure hunter or ghost hunters, also see a reading trend through the graph.
Simple app in your device called Gauss Meter are used for measuring the Earth's magnetic field but can't detect silver, gold, copper coins (non-ferrous - no magnetic field).
This Magnetometer app require a magnetic sensor otherwise does not work.
Enjoy !
金属探测器 - 磁EMF - 使用内置于智能手机的磁性传感器测量磁场值。
现在你可以很容易地找到那些隐藏在地下的金属物体,墙后面等,或者是一个寻宝猎人或幽灵猎人,又见通过图形阅读趋势。
在装置称为高斯计简单的应用程序被用于测量地球磁场,但无法检测到银,金,铜硬币(非铁 - 无磁场)。
这种磁力应用需要一个磁传感器,否则不能正常工作。
尽情享受吧!
