Vlf Metal Detector Circuit
Phase shift provides vlf based metal detectors with a capability called discrimination.
Vlf metal detector circuit. Vlf is today the most common metal detector and the one that works best as an all round detector. This metal detector is based on an arduino microcontroller and a smartphone. Since most metals vary in both inductance and resistance a vlf metal detector examines the amount of phase shift using a pair of electronic circuits called phase demodulators and compares it with the average for a particular type of metal. Just follow the tutorials step by step and if you have any questions contact us.
This metal detector is able to detect. Diy sensitive vlf metal detector with smartphone detects a small metal coin at 25 cm and pot lid at 1m distance. This is the vlf receiver circuit that i ve upgraded and modified it senses ac fields lightening and even receives ship and aircraft radio too. Here you will find all the necessary tutorials.
Vlf technology is a good detector that meets most detector needs. This metal detector is capable of detecting small metal objects at great distances. Metal detector smart hunter is a project that will help you build a powerful vlf metal detector. Works as described above with two coils one transmitting and one receiving.
I ve even used a gravity wave detector circuit added to it and also other experimental circuits. And the best part is that it is very simple and can be made by anyone who has. Vlf detectors usually operate at a frequency in the range of 3khz 30khz.
