Nov 10, 2009· Metal detector circuit diagrams and projects Note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced
Metal detector is a device used to detect the presence of a metal in its proximity without touching it This project explains the concept of detecting the presence of a metal using the method of inductive sensing The basic concept used is that the presence of a metal can vary the inductance value of an inductor The prototype discussed here is a modified version of an inductance meter, which .
