3月3日 的 Metal Detector 應用程式分析

Metal Detector is an Android application that detects the presence of metal nearby by measuring the magnetic field value. This useful tool uses the magnetic sensor built into your mobile device and shows the magnetic field level in μT (microtesla). The magnetic field level (EMF) in nature is about 49 μT (microtesla) or 490 mG (milligauss); 1 μT = 10 mG. If any metal is nearby, the value of the magnetic field will increase. Metal Detector allows you to identify any metal object in the area because all metals generate a magnetic field whose strength can be measured with this tool. The usage is simple: launch this app on your mobile device and move it around. You will see that the magnetic field level shown on the screen is constantly fluctuating. Colorful lines represent the three dimensions and the numbers on top show the value of the magnetic field level (EMF). The chart will increase, and the device will vibrate and make sounds, announcing that metal is close. You can change the sensitivity of vibration and sound effects in the settings. You might use the Metal Detector to find electrical wires in walls (like a stud finder), iron pipes on the ground... or pretend it's a ghost detector and scare someone! You can also use this magnetometer as a scanner to find hidden devices – cameras, microphones or voice recorders! Metal Detector is available in the language set on your phone – now also in Russian, Spanish, and Indonesian! You can also find it in Portuguese, Turkish, and French. Now the app also has its versions in Arabic and Farsi! If you enjoy the app and want even more – you can get a pro version! Check it out in the application menu. The accuracy of the tool depends entirely on the sensor in your mobile device. Please note that due to electromagnetic waves, the magnetic sensor is affected by electronic equipment. Metal Detector cannot detect gold, silver, and coins made of copper. They are classified as non-ferrous, which has no magnetic field. But maybe you will find a metal box with some treasure inside! Try this useful tool and other apps from the Netigen Tools series! Attention! Not every model of a smartphone has a magnetic field sensor. If your device does not have one, the application will not work. Sorry for this inconvenience.
