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.
Design and build the detector.Decide how you will build a detector that moves around the surface.Think about how to keep the metal shards from falling off or out of the detector.Choose the materials and build the detector.Tip metal shards are very difficult to clean off a magnet, so keep them in an area away from magnets until you place.
The circuit can sense a soda can at a depth of six inches and metal pipes at an even greater distance.The unit is powered by two 9v batteries in series.The detector has a current draw of approximately 9 ma at 18 vdc.As a result, the batteries should last a long time.Figure 1.Four transistor metal detector schematic.
Hello to all of the electronic enthusiasts and diy lovers out there the following article is made to simplify the basics of electronics.In it, you will find a walk-through guide of how to build your own metal detector.Keep in mind that this tool will not have the same ability as a commercial metal detector- for example finding hidden gold beneath the earths surface.
How to build metal detector.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.
