【實用工具app】金屬探測器|最夯免費app-綠色工廠好玩App

With Metal HuntR users can detect metal objects, electric devices and wires in their environment. The application uses the magnetic field sensor to measure the strength of the magnetic field. Earth's magnetic field strength is about 49 uT, so the sensor will show this value, if there is no object with magnetic field near the device. If an object with magnetic field appears near the device (like metal or electric devices), than the sensor values will rise.

If the app shows strangely high or low values, calibration is needed (see: Calibration menu).
