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.
Metal detector sensor interfacing with arduino.
The prototype discussed here is a modified version of an inductance meter which.
Build a simple arduino based metal detector project using coil and capacitor.
Find here the complete project tutorial with circuit diagram and code.
Metal detector is a device used to detect the presence of a metal in its proximity without touching it.
Arduino metal detector wiring the sensor coil 100μh is made as 40mm in diameter and 50 turns by 0 4 mm insulated copper wire and there is no need for core inside the coil.
This project explains the concept of detecting the presence of a metal using the method of inductive sensing.
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.
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.
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.
