Finding metals using your cell phone

Did you know it is possible find metals using your cell phone?

Yes, it is possible, as there are now applications that help in the search for metals, in addition to the already known electronic and portable detectors.

Metal detectors are portable devices that are capable of detecting the presence of nearby metals, such as objects buried underground.

Detectors are basically a device that contains a sensor probe, which when it is close to a metal object, emits a sound, which makes it possible to determine where it is.

Typically, the device gives you a distance indication, and the closer you are to the metal, the louder the sound in the headphones will be.

To turn your cell phone into a metal detector, your device must have gyroscope, geomagnetic and accelerometer sensors.

If you can't afford to buy a metal detector or can't make a homemade detector, this is the best option.

This device will help you learn to detect metals, but it will depend on the type and quality of your device.

This application has the function of measuring the value of the magnetic field, using the sensor that is connected to your cell phone.

Metal Detector

THE Metal Detector is a tool that is available for Android cell phones, which detects metals.

The program works like a kind of magnet, using a digital compass that exists in the cell phone, which is capable of detecting metals anywhere, and for it to work correctly, simply point the cell phone at a metal object so that the device recognizes it.

After installation, the device searches for metal objects nearby, scans the object and after a few seconds it vibrates and appears on the cell phone screen.

It is also possible to define whether the device will vibrate or emit a sound, which the user can change in the application settings when installing it.

On the other hand, the higher the sensitivity of the sound emitted, the more battery will be used on your cell phone.

The search for identifying metals is generally carried out by banks, currency exchanges, concert halls and several other entities, in order to guarantee the security of the respective locations.

According to users of the Metal Detector app, the tool is nothing more than a joke to interact with friends and family, as the wrong objects have already been detected by the app, so the app works, but it should never be replaced by professional detectors, used in airports, banks, armed forces and other institutions.

The application works, but it is not reliable in places that require a professional device. It only serves to distract the user and pass the time.

There are a variety of metal detectors on the market, specific for each function, there are even underwater detectors, to detect metals at the bottom of the sea.

Metal detectors work through a magnetic field, which, when in contact with the object, induces an electric current, just as the object also has a field that causes interference in the detector.

In this way, the appropriate variation is observed in a specific meter that will give a signal when the materials come into contact.

In short, the detectors work by electromagnetism, consisting of a transmitter and a receiver.

The transmitter consists of copper wires wrapped around a metal material, powered by an external power source.

The receiver consists of a coil wound on iron, but without power supply.

Now it’s time to enjoy every moment of your pregnancy, while you wait for the special day for your baby to be born.
