Metal Detector Circuit. I always wanted to make a metal detector seeing how cool it was in all Hollywood, Bollywood movies. One thing I realised is; things aren't as difficult as you think it is. After all, I found that a metal detector is really simple and easy to make. So in this post, I am sharing with you "How to make a metal detector"
10-03-2014· There are a lot of metal detector or gold detector on the marketplace that claimed to be capable of 1.5-3.5 detecting depth or even greater. But if you think this means that the a gold metal detector for 3.5 meters depth can actually always go down to 3.5m depth in any occasion when detecting underground buried treasure, you are possibly have a misunderstanding of the description.
06-01-2018· We have used an Arduino Nano for controlling whole this Metal Detector Project. A LED and Buzzer are used as metal detection indicator. A Coil and capacitor is used for the detection of metals. A signal diode is also used for reducing the voltage. And a resistor for limiting the current to the Arduino pin. Working Explanation: Working of this Arduino Metal Detector is bit tricky.
Besides the metal detector, several other interesting projects have been tried by others for illustrating concepts of electromagnetics: a capacitive weight sensor [3], a capacitive rain gauge, an electric field probe, a non-contact AC current meter [4] and an electromagnetic crane [10].

31-07-2017· Metal Detector Circuit Explanation. When the LC circuit that is L1 and C1 has got any resonating frequency from any metal which is near to it, electric field will be created which will lead to induces current in the coil and changes in the signal flow through the coil. Variable resistor is used to change the proximity sensor value equal to the ...
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).
