BFO detectors are not as sensitive as IB types and have to be fitted with a ... METAL DETECTOR ... the transmitter section of the circuit. Q6 is a which operates as a relaxation oscillator, the audio note produced being determined by R16 and C18. The specified
The most common type of IB detectors are the single frequency metal detectors. Metal detector set to work at only one frequency, have the best chances to achieve good depth penetration and discrimination accuracy. The next popular type of metal detectors, capable to compete for better depth, are the PI metal detectors.
In this project we are going to design a simple metal detector circuit. There are so many metal detector designs but most of them are complex in design so here we are going to design a simple metal detector circuit using 555 Timer IC. Before going further we need to understand concept of inductor and RLC circuits. Let us first talk about inductors.
