Our mobile is a complete Swiss Army knife, gutter with functions of all kinds and some as curious as useful. This time we are going to show you how to make your mobile have the ability to detect metals, a function that does not need any accessory and is only based on the sensors it has inside. As in other cases, its possibilities are many, but they are not always designed as we would like.
You may think when you come across applications of this style by the Android application stores or the iOS operating system that this is a joke. At other times it can be, but in this case we are going to show you which apps work best and with which you can check it yourself and find out where the metals are around you.
Easy, fast and simple to use
To get our mobile to become a metal detector, we are going to need a smartphone that has a compass , which is the vast majority or otherwise we would not know with the GPS of our mobile to what point we are looking. Once we are sure of this, we will only have to download the corresponding application:
- Metal detector for Android phones
- Tesla – Metal detector for iPhone
Both applications work in the same way and that is that design is not the strong point of either of them, since the only function we need is a level that shows us the magnetic variations when approaching a metal. After installing it we just have to go to a metal product or we can even check it with a TV.
How the mobile can work as a metal detector
The explanation to understand this is based on the compass, one of the many sensors that we have in the mobile. We remember that compasses have been working for many years and they are not a very complex technology since it is a magnet that is attracted by the position of the poles and varies if other metals are closer. The compass of the mobile has this same capacity and being inside our mobile, this change will be reflected in the app that we have downloaded.
Through the fluctuations that occur in the magnetic field of our mobile , this change occurs that we see in the application. Depending on the size of the metal and the mobile’s own sensor, metal detection will be more or less accurate, but what is certain is that it will work if we bring it closer to large household appliances. In small products it will be more difficult, but at least as entertainment and curiosity it will be worth us.
