Wall Scanner uses your devices magnetic sensor to measure the intensity of magnetic field values from electrical wires and metallic pipes and turns your phone to a high efficiency metal detector.
Data is displayed in the gauge. Nature magnetic field ranges from 23 to 63 µT. Any higher or low measurement is an indication of a wire or pipe in the wall.
The accuracy Depends on of the sensor of your phone, locate metal, AC wires and deeply embedded objects behind floor, ceiling, wall.
Using the App
1. When the app start, it will ask you the calibrate the magnetic sensor, by shaking the phone UP and Down and Left to Right for about 5 seconds.
2. After the sensor is calibrated the magnetic field gauge will display
3. Place the phone on a wall and move it around. When there is a metal pipe or wire it will change the magnetic field and the gauge will move up or down. Warning you
Insulation and depth of an object may cause that it will not be detected.
