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.
Metal detector sensor interfacing with arduino.
The prototype discussed here is a modified version of an inductance meter which.
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.
The basic concept used is that the presence of a metal can vary the inductance value of an inductor.
A lightning detector for arduino project tutorial by runtimeprojects.
Find here the complete project tutorial with circuit diagram and code.
This project explains the concept of detecting the presence of a metal using the method of inductive sensing.
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.
Metal detector is a device used to detect the presence of a metal in its proximity without touching it.
Build a simple arduino based metal detector project using coil and capacitor.
