You can find a metal detector at airports, theaters and various other public places. They 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. There are so many metal detector designs but most of them are complex in design so . Read this post to get good idea about circuit diagram of metal detector. This Pin was discovered by Grzegorz Snug.

Discover (and save!) your own Pins on Pinterest. The other day when I was searching instructables I come across on interesting and simple circuit for metal detector. It is build with 55 coil and few other components.

Main debate was: does it really work? After quick research I found this video that proof it works. Simple metal detector circuit diagram with 5timer and applications. A simple metal detector circuit diagram and schematic using a single transistor and a radio.

Traditional BFO (beat-frequency oscillator) metal detectors overcome this problem by incorporating another tank circuit with a fixed frequency equal to the. The heart of this diy metal detector circuit is the CS209A IC. As shown, the circuit oscillates at around 230kHz. One may also experiment with the frequency by changing the value of C1. Metal Detector circuit diagram.

A Faraday shield may be added to reduce ground effect and capacitive coupling, and this is wired to 0V. This article discusses about what is metal detector, metal detector circuit diagram , metal detector working, types of metal detectors with applications. This is the basic effect that the Beat Frequency Oscillator (BFO) type of metal detector uses to detect all metals. Figure shows a block diagram of the circuits making up a typical BFO detector. Build your own metal detector an ideal school college or hobby project.

Looking for a simple but effective metal detector circuit for coins, jewelry, and more? This tutorial will show you how to make a metal detector circuit with a few electronic parts. Here, we teach you how to make a metal detector circuit with which you can hunt hidden treasure. This simple metal detector circuit can also be used to detect buried cable or . NE55 Simple Circuit Diagram.

This is a simple metal detector circuit , Can find various metal and adjustable sensitivity Easy to use to place near metal. The Beat-frequency oscillator (BFO) is the simplest (and oldest) type of metal detector technology and is a good starting point for learning how metal detectors work. The basic beat- frequency metal detector employs two radio frequency oscillators which are tuned . The operation of metal detectors is based upon the principles of electromagnetic induction.

The single-coil detector illustrated below is a simplified version of one used in a real metal detector.
