HTC GPS software : HTC Metal Detector |
 |
The built-in compass uses the earth's magnetic field to calculate the deviation from magnetic north. As with every compass, if you put a piece of metal nearby, it gets deviated. That's what i use here to detect metal.
Testing: Place your device flat on a surface. After starting the app, the gauge should show zero. If it doesn't, take your device and write a couple of "eights" in the air (this is to get rid of magnetism which might get stuck in the sensors).>
Then use a pair of scissor or something the like and move it slowly to the right side of your device. At a distance of approx. 5 cm. the gauge should start to move. Take your device and move it with its right side near metals, and see if the gauge shows values. |
