Vlf Ib Metal Detector With Microcontroller Unit Reviews

From ancient times people are attracted instruments to search for hidden metal objects. The reasons for this interest is different. Builders are interested in location of the metal reinforcement in the walls, aspirants dream of finding treasure in the ruins of the old building of the pitcher with gold coins, sappers were searching for unexploded “gifts” of past wars. All these people are United by the desire to have an inexpensive, compact and economical unit, which will help them to discover through the layer of Earth or concrete metal objects and, if possible, determine what metal they contain. If you exclude exotic methods, the vast majority of such devices is based on electronic devices, reacting to changing metal objects electromagnetic field by the search appliance.

Design and Implementation of Microcontroller Based Metal Detector, an electronic surveillance system will be considered using a metal detector, A simple metal detector circuit diagram and schematic using a single transistor and a radio. This metal detector sensor project is easy to make, metal detector robot using pic microcontroller,this robot is designed for metal detection in places where human being can’t reach easily.

Most often as a coil excitation and sensor device used framework coil consisting of several hundred turns of copper wire in the circuit of oscillator. In such devices is the effect that when the metal object to the coil inductance changes its and, as a consequence, the frequency of the oscillator. However, in General ferromagnetic objects (iron, cast iron) lower frequency, (copper, gold, aluminium) increase the frequency of generation. Registering magnitude and sign of the deviation of frequency, it can be concluded on the type of metal object in the search area of the frame. The main differences between most types of metal detectors are ways of registration of change of frequency.
