The basic concept used is that the presence of a metal can vary the inductance value of an inductor.
Metal detector sensor interfacing with arduino.
Find here the complete project tutorial with circuit diagram and code.
Build a simple arduino based metal detector project using coil and capacitor.
The prototype discussed here is a modified version of an inductance meter which.
Metal detector is a device used to detect the presence of a metal in its proximity without touching it.
Wiring a metal detector with npn proximity sensor on arduino in this illustration we will going to wire the npn inductive proximity sensor to detect metal or any metal objects this device also can be used as a metal detector screening when people walking through the entrance to find metal objects.
This project explains the concept of detecting the presence of a metal using the method of inductive sensing.
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.
Arduino project to detect lightnings using electromagnetic radiation with frequencies from 7 9khz.
Here the ic cs209a provides two outputs as out1 from pin 4 which is normally high and out2 from pin 5 whis is normally low you can use any one or both with arduino.
