HD Metal detector is a mobile application by TECH_BASE aimed at detecting the presence of metals (Ferromagnetic metals) in the nearby surroundings. Below are some of the uses of HD Metal Detector:

1. Detecting metals in the surroundings 
2. Detecting buried ferrous materials (materials containing iron) such as iron pipes
3. Detecting electric cables inside walls
4. Used by Ghost hunters to pick up spikes in Electromagnetic radiations
5. It can be used as a security device to scan for presence of metallic objects like Guns,
Knives etc.

This app require Magnetic field sensor (magnetometer) in the phone installed on in other to work. The sensor is a hardware component that is usually integrated into most mobile device. 

In a nutshell, HD Metal detector makes use of the sensor is to measure variations in the Earth’s magnetic field (magnetic field level in nature is around 49 µT.) The presence of ferrous metals or other materials containing electric and magnetic properties causes distortions in the field. This  result in magnetic anomalies that are then picked up by the mobile application. 

NOTE: sensor accuracy is dependent on the quality of the magnetic field sensor incorporated in the phone. More so, interference from electromagnetic sources can distort readings in the app leading to inaccurate metal detection. example includes:

* Magnet in the speaker of the mobile phone or in an external speaker in the surroundings
* Presence of electronics like laptops, electric lamps, batteries etc.
* Incoming and outgoing calls, mobile data usage, WiFi etc. These effects can be reduced 
by putting the mobile device in flight mode while using the app
* Variations in the Earth's magnetic field due to solar wind and magnetic storms causes 
anomalies in the Earth's magnetic field leading to false detection of metals.
HD金属探测器是TECH_BASE的移动应用程序，旨在探测附近环境中是否存在金属（铁磁性金属）。以下是高清金属探测器的一些用途：

1.检测周围环境中的金属
2.探测铁管等埋藏的含铁材料（含铁的材料）
3.检测墙壁内的电缆
4.被幽灵猎手用来拾取电磁辐射中的尖峰
5.它可以用作一种安全设备，以扫描枪，
    刀等

此应用需要在手机上其他安装的磁场传感器（磁力计）上才能工作。传感器是通常集成到大多数移动设备中的硬件组件。

简而言之，高清金属探测器利用传感器来测量地球磁场的变化（自然界中的磁场水平约为49 µT。）黑色金属或其他包含电和磁特性的材料的存在会导致磁场畸变。领域。这导致磁异常，然后由移动应用程序拾取。

注意：传感器的准确性取决于电话中内置的磁场传感器的质量。更重要的是，来自电磁源的干扰可能会使应用程序中的读数失真，从而导致金属检测不准确。示例包括：

*手机扬声器或周围环境中的外部扬声器中的磁铁
*存在笔记本电脑，电灯，电池等电子产品
*来电和去电，移动数据使用量，WiFi等。这些影响可以减少
   通过在使用应用程序时将移动设备置于飞行模式
*由于太阳风和磁暴引起的地球磁场变化会导致
   地球磁场的异常导致对金属的错误检测。
