Easy to build pulse induction metal detector with DSP ...

Introduction to Metal DetectionSearch Coil DesignThe Discharge Curve and DiscriminationPower Supply DesignMost metal detectors work on the fact that metals in a magnetic field change the behavior of the field. There are two general approaches to detect these changes. In one approach, an alternating current is provided to a transmit coil. A receive coil is used to pick up the magnetic field generated by the transmitter. If a piece of metal comes inside the range of the magnetic field lines, the receive coil can detect a change in both amplit…在lammertbies.nl上
