If you do a little bit well, I brought you a free application capable of turn our Android device into a professional digital meterNow, in this new video I bring you another tool that many of you are sure to love. And it is that this time I am going to recommend an equally free application that you will get turn our Android into a metal detector.
If you heard correctly, with the totally free application that I recommend in the attached video that I leave you in this post, we are going to get turn Android into a metal detector, a metal detector that we thoroughly test to teach both the operation of the application and its reliability or effectiveness.
If you are suspicious of series as I usually am and when you see applications of the metal detector type in the Google Play Store you will laugh out loud like me, then I advise you to watch the video that I have left you right at the beginning of this article since in it I thoroughly test one of the few metal detector type apps that works really well to be honest.
The application that responds to the name of simply Metal detector, is an app that we can download directly and for free from the Google Play Store, which is the official application store for Android, an app that I leave a direct link to Google Play for you to download and Try as I have done on my Huawei P20 PRO.

But how does the application really work?
If you are not sure if your Android terminal has this type of built-in sensor, you can always go to see its technical specifications on the manufacturer's website.
How to turn your Android into a metal detector
To give you the idea, Most of the well-known brands in their mid-range and high-range terminals usually incorporate this sensor as standard, for example in the P range of Huawei as is the case of the Huawei P20 Pro, the terminal with which I demonstrate in the video, has this type of sensor that by the way works very well with the metal detector application.
This application measures the magnetic field with a built-in magnetic sensor.
The magnetic field level (EMF) in nature is approximately 49μT (micro tesla) or 490mG (milli gauss); 1μT = 10mG. When any metal (steel, iron) is close, the level of the magnetic field will increase.
The metal detector application offers us the possibility of set the measurement sensitivity of electromagnetic waves, as well as enabling or disabling an audible alarm with which to warn us of the proximity of these electromagnetic waves that suggest the presence of metal objects.
Keep in mind that the precision of the application is always linked to the quality and precision of the magnetic sensor that we have installed in our Android deviceThis, in addition to the possible interferences that the electromagnetic fields caused by the electrical appliances that we have in our home, may cause, good examples are televisions, microwaves and devices such as wifi routers and devices with bluetooth connectivity.
Undoubtedly a very, very curious application, which, added to a good selfie stick, will give us the possibility of being able to turn our Android into a metal detector completely free of charge.
In the speaker what it detects is the magnet of the speaker, and in the knife in the handle it does not detect anything, I do not think it is used to detect pipes that are inside the walls
