A Highly Sensitive Low-cost, Small-sized Device for Measuring Weak Magnetic Fields

A highly sensitive low-cost, and small-sized device has been developed for measuring weak magnetic fields. The microcontroller-based device is capable of reading magnetic fields of range ±800 μT with a resolution of 0.07 μT. The permissible accuracy of the device covering a full range of measurements is less than 1.5%. The device is highly compact and can display the magnitude and direction of magnetic fields

1. Data storage centers

2. Healthcare (Studying Geopathic stress lines)

3. Aviation sector, Satellites, Military detection (Earth's magnetic field)

4. Consumer electronics

5. Laboratory and industries (calibration)

The developed low-cost and pocket-sized device having enhanced accuracy can have numerous applications, such as detecting the earth's magnetic field, studying geopathic stress lines, calibrating similar magnetometers, data storage centers consumer electronics, and other utilization in aviation, military detection and space.
