May 14, 2015· How these two concepts are used together for a metal detector circuit, is explained in working section of this project. Circuit Components +9 supply voltage; 555 IC; 47KΩ resistor; 2.2µF capacitor (2 pieces) Speaker (8Ω) 170Turns of 10cm diameter coil (any gauge would work) Circuit Diagram and Working. The figure shows the circuit diagram of
Mar 04, 2008· A simple metal detector circuit diagram and schematic using a single transistor and a radio. This metal detector/sensor project is easy to make and is an application of Colpitts oscillator.
Metal Detector Circuit Schematic Diagram. Below is the complete electronic circuit for the metal detector that we are building: Inductor L1- The inductor L1 forms a parallel circuit with the capacitor C1 to form an LC parallel circuit. When a signal that oscillates at several KHz passes through this circuit, the signal creates an electric field
Circuit diagram. The circuit described here is that of a metal detector. The opera- tion of the circuit is based on superheterodyning principle which is commonly used in superhet receivers. The circuit utilises two RF oscillators. The frequencies of both oscillators are fixed at 5.5 MHz.
Jul 16, 2011· This homemade metal detector circuit will help you find objects composed of materials with relatively high magnetic permeability. It is not suitable for buried coins discovery that is not sensitive enough but you can detect pirates treasures! The metal detector is powered by 2 x 9V batteries, each of it charges with 15 mA.

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.

These metal detector circuits are being used in plenty of places. Most of the security officers use it to detect metal devices like guns, knives, etc. A metal detector is a circuit that senses any metallic object close-by. These metal objects are very useful to detect the presence of any hidden object. A simple metal detector uses a 555 Timer
Metal detector circuit diagram,The metal detector is a relatively simple device, an electronic circuit that provides good sensitivity and stability. A distinctive feature of this device is the low operating frequency. Metal detector coil operates at a frequency of 3 kHz.
The metal detector circuit shown here must represent the limits of simplicity for a metal detector, yet the design works surprisingly well. It uses just one 40106 hex Schmitt inverter IC, a capacitor and a search coil and of course the batteries.
Simple Metal Detector: The other day when I was searching instructables I come across on interesting and simple circuit for metal detector. It is build with 555, coil and few other components. Instructable that inspire me to do this project was this one. Main debate was:
Metal Detector coils that is used for the thickness of the wire is 0.3 mm, but the diameter of the circle The author used to wrap prepared wire 0.7 mm 15cm.The number of rounds between 25 16cm (15.5 cm) after coil winding, paper tape, or electrical tape is wrapped with. with the coin of the metal detector in the test video shows how the circuit works
For this metal detector project, we will be using an Arduino to process the oscillation signal instead of offsetting the oscillation with a second tank circuit. The Arduino will store the fixed frequency and continuously compare the incoming frequency of the detector circuit with the stored frequency (more on the Arduino program below).
Metal Detector is a security device which is used for detecting metals which can be harmful, at various places like Airports, shopping malls, cinemas etc. Previously we have made a very simple Metal detector without a microcontroller, now we are building the Metal Detector using Arduino.In this project, we are going to use a coil and capacitor which will be responsible for the detection of metals.

The reason this works is because the loud tone coming from the radio is the calculators electronic circuit producing a radio frequency signal. That being said, the radio waves from the calculator reflect off the spoon and are heard on the AM radio. And there you have it, A cheap and easy homemade metal detector. Enjoy, and have fun!
