Abstract This project focuses on the adaptation, simulation and construction of a commonly available schematic for a Pulse Induction (PI) metal detector.
How this metal detector works is that it uses an IC that generates an AC signal that goes through a coil. Metal objects are objects which conduct electricity, so a current can be induced in these metal objects. When the coil in the metal detector comes near a metal object, the electromagnetic field in the coil induces currents in the metal ...

Page created December, 2010. This model could be termed a modern remake of the old VLF/TR detector. It looks eerily similar to Bounty Hunter's current "VLF" model.
Electronic circuits that use the ic 555 Timer, A simple metal detector electronic project can be designed using a simple 555 timer circuit. As you can see in the schematic circuit, this project requires some external electronic electronic parts.
Metal detectors are used for the safety of people to detect anyone carrying a metal (Arms etc). In this project we are going to design a simple metal detector circuit.

Dec 28, 2013· Since metal detecting is long over for this season, why not upload some videos from a few years ago when I had my old channel "MetalDudz" going!
This metal detector electronic project schematic circuit is designed using a simple 555 timer integrated circuit. As you can see in the schematic circuit, this metal detector electronic project requires few external electronic parts. .
Example VLF design: Heathkit Groundtrack GR-1290 VLF metal detector Pulse Induction (PI) metal detectors are sending repeated pulses of electrical current to the search coil, producing a magnetic field. The coil transmits a pulse toward the ground, generating an answering pulse from the target object. A sampling circuit measures the …
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere.
Very Low Frequency (VLF) Detector Last Updated on July 8, 2018 by Swag 7 Comments Low frequencies predominantly cover our earth's atmosphere. This range of frequency may be created by many different sources which may be quite unknown and strange, a VLF sensor equipment can be made to trace these frequencies for …
A metal detector circuit is located on the robot's vehicle. The operation of the robot vehicle is carried out if it detects any metal objects below, then the robotic vehicle detects the metal and generates a buzzer sound to give an alert to the operator of a possible metal object near to its path.
Very low frequency (VLF), also known as induction balance, is the most popular detector technology in use today. In a VLF metal detector, there are two distinct coils: Transmitter coil - This is the outer coil loop. Within it is a coil of wire.
Dec 09, 2015· Yet VLF detectors maxed out for usable depth by at least 1990 if not before. I have not used any VLF metal detector since 1990 that got more depth on coins than my Compass Gold Scanner Pro. The only real improvement we have seen and are still seeing is in the ability to find and correctly identify items that are masked by the …
Metal detector is a device that can detect metal, the basics can make a sound when it is near some metal, and the more advanced can tell what kin of metal and how deep it is down, they are using different detecting principles.
The Proximity Detector IC TDA0161 based Metal Detector Circuit is a very simple and easy to construct metal detector that can be used to detect small metals in our homes, offices and gardens. There is need for any microcontroller as the Proximity Sensor will be sufficient to implement the project.
Page 1 Metal detector uses single IC RACHEL AND STEVE HAGEMAN, HEWLETT-PACKARD, SANTA ROSA, CA The original application of the circuit in Figure 1 was to locate coins, but it applies wherever you need to locate
VLF (Very Low Frequency) is a conventional single frequency sine wave transmission technology. This is the traditional type of technology used in most basic metal detectors. Single frequency sine wave detectors create an electro-magnetic field, which is transmitted into the ground in a continuous wave. While the basic way that the signal …
