description: This work is devoted to the study of the principle of operation of modern and most common metal detectors. Tasks that were solved during the study: 1. Study of the number of turns and wire diameter from the metal detection distance. 2. Finding ways to increase the sensitivity of the circuit. 3. Study of the influence of "non-ferrous" and "ferrous" metal on the shape of signals at different points of the circuit. 4. Finding the optimal parameters of the electronic elements of the circuit. 5. Simulation and study of signals of the equivalent circuit of a metal detector. The work was carried out on the basis of a pulse circuit of a metal detector. Simulation of the simplest equivalent circuit of a metal detector was made in the Qucs program. Several experiments were carried out with testing coils of various diameters and wire cross-sections. The operation of the circuit with various operational amplifiers, namely K157UD2 and TL084CN, was also tested, and the signals at different points of the circuit were studied. As a result of studying the pulse circuit, the optimal ratings of its components and coil parameters were found. Signals and their changes are investigated depending on the size, shape, type and position of the metal relative to the coil. It was also said that using a system of discriminatory practices of metals is impossible. The results obtained can be used for further circuits with a microcontroller for more accurate detection.
