Step 3: Building. I found a good example of a PI detector on the site of the N.E.C.O. projects. This metal detector is a symbiosis of Arduino and Android. On the Play Store, you can download the free version of the application "Spirit PI", which is fully functional, but you can also buy a pro version that has several great options.
echo lasts longer. In a PI metal detector, the magnetic fields from target objects add their "echo" to the reflected pulse, making it last a fraction longer than it would without them. A sampling circuit in the metal detector is set to monitor the length of the reflected pulse. By comparing it to the expected length, the circuit can determine if

I used an Arduino UNO to program a DIP ATMega328. I then removed the ATMega328 from the development board and embedded into a perfboard along with the rest of the circuit. The Colpitts oscillator, on the bottom left on the diagram, feeds the oscillation into counter 1 (pin T1) of … See more
Tune in. Turn on the AM or AM/FM radio and set the frequency as far to the right as you can, and then turn the volume up so that all you can hear is static. Move around. Turn on the calculator and ...
Now, let's build a metal detector using a proximity sensor that can sense ferrous and non-ferrous objects by using both inductive and capacitive proximity sensors. Circuit diagram. The inductive sensor is connected to Arduino UNO's digital pin#8. This sensor's output is a fixed voltage signal. The capacitive sensor's output is connected ...

As you can see in the video, the results are surprisingly good. Without the presence of a metal, device is perfectly stable. The range is relatively large and for example, a metal cover with a diameter of 15 cm is detected at a distance of more than 30 cm. Larger metal objects are detected at distances greater than 40-50cm.
A simple metal detector circuit diagram and schematic using a single transistor and a radio. This metal detector/sensor project is easy …
Metal detector circuits use an oscillator that produces alternating currents. An eddy current passes through the metal when active. Hence, the current produced passes through a coil. Doing this creates an alternating magnetic field. The magnetic field attracts the metal closets to the coil. As a result, the metal changes the magnetic field ...
Building the detector is quite easy. This can be done either on a breadboard (sticking to the original circuit) or by soldering the parts on a PCB. The D13 LED on the Arduino Nano board is used as an indication …
When you are ready to start soldering, install the parts, one at a time, to the top side of the board (Fig. 2). The wire pigtails will protrude through to the copper underside. Secure each wire with a drop of solder to the copper adjacent to the hole. Double-check polarity of capacitor installation.
Metal Detector Circuit. March 24, 2024. By Ravi Teja. Metal detector is a very common device that is used for checking persons, luggage or bags in shopping malls, hotels, cinema halls, etc. to ensure that person is not carrying any metals or illegal things like guns, bombs etc. Metal Detectors detect the presence of metals.
Step 1 – The Circuit Board. There are several diagrams available if you want to build your own circuit board. The first step in making your metal detector is to build …
Building the detector is quite easy. This can be done either on a breadboard (sticking to the original circuit) or by soldering the parts on a PCB. The D13 LED on the Arduino Nano board is used as an indication for metal. Unsing a breadboard is the fastest way to the working detector.
MODIFYING THE CIRCUIT The circuit can be made much more sensitive by replacing the printed circuit coil with 50 turns of wire (0.25mm), 70mm diameter for coil L1 and 5 turns of the same wire for coil L2. The 100R mini trim pot needs to replaced with 1k mini trim pot. Turn the circuit ON and the buzzer will squeal.
1. Tune the radio to highest band on the AM setting. Make sure you are not tuned to a station. You should hear the static tone clearly and steadily. This will allow you to hear any differences in the tone when your device detects a metal object. [1] 2. Assemble the search head. Turn on your calculator.
