9 Aralıkiçin Magnetscape uygulama analizi

"Magnetscape" is a new real-time measurement app that observes invisible magnetic fields using the iPhone's built-in magnetic sensor. There are various magnetic fields around us. For instance, the magnetic field fluctuates even when large motors, compressors or metal are nearby. The Earth's magnetic field exists even in empty places, and we are constantly affected by it. "Magnetscape" enables real-time monitoring of surrounding magnetic fields and can be utilized for various applications in real life. It can be used for investigating static magnetic fields, searching weak electromagnetic fields within alternating magnetic fields, locating metals and more. This app features three measurement modes for magnetic field observation, allowing you to use it according to your needs. - Scope Displays the magnitude and direction of the magnetic field graphically. The magnetic flux density of the magnetic field is expressed by the size and color of the graphic circle. The position of the graphic circle on the display moves according to the polarity of the magnetic source. The polarity is attracted to the N pole if it is in the same direction as the geomagnetic field. If it is the opposite (S pole), the polarity will be reversed away . If there is no metal or magnetic field nearby, it will be shifted in the direction of the geomagnetism (N pole). - Time Trace the raw data from the magnetic sensor and its corrected data. It is a time displacement graph of each axis value (Bx, By, and Bz) and the composite magnetic flux density (Bcomp) in three-dimensional space. You can scroll up to 180 seconds. - FFT Perform frequency analysis on the changing magnetic field. It displays the result of FFT analysis of the composite magnetic flux density. Horizontal axis: Frequency 1 - 16 Hz (0.5 Hz) Vertical axis: dB (ratio to default standard value 45 μT). Reference value can be set in units of 45 ± 15 μT / 1 μT. Features: - Graphical display of magnetic field observation by magnetic sensor (Scope) - Time displacement graph display of magnetic field observation (Time) - FFT analysis (FFT) - Magnetic field observation 　X axis: Intensity (Bx) of the magnetic field of (the right direction toward the screen) 　Y axis: Intensity (By) of the magnetic field of (upward toward the screen) 　Z axis: Magnetic field strength (Bz) in the of (vertical upward direction of the screen) 　Composite magnetic flux density: The magnetic field strength (Bcomp) taking into account all three components of the x-axis, y-axis and z-axis. 　Sampling frequency: 32 Hz 　Unit of observation value: uT - Measurement time: 3 minutes - Alert function: A warning message will be displayed if the composite magnetic flux density exceeds 300 μT. - Alert sound function. (Sound Off/On) - Peak hold function on FFT mode. - Angle display function in Scope mode (Angle) - Clock display function in Scope mode. Notes: - The display value of this application is the RAW output data from the magnetic sensor itself. It does not perform any processing such as filter processing within the application. - Since the magnetic sensor is a sensitive device, the internal reference value of the magnetic sensor may be disturbed if exposed to extremely strong magnets and magnetic fields for a long time. - If the reference value of the magnetic sensor becomes incorrect, the magnetic sensor will automatically readjust after you stop the application and leave it for a while. If the magnetic sensor remains unstable, please try the electronic compass calibration and reset procedure. Please visit our iOS App Support page for more information on this app.
