The power supply element 4 can supply power to the Hall sensing element 2, the data processing element 5, the data output element 6 and the geomagnetic measurement element 7. The Hall sensing element 2, the data output element 6 and the geomagnetic measurement element 7 are all connected to the data processing element 5. Taking the Hall sensing element 2 as an example, a power line and a signal output line extend from the Hall sensing element 2, wherein the power line is connected to the power supply element 4, and the signal output line is connected to the data processing element 5. When in use, the Hall sensing element 2 detects the signal change on the flexible magnetic conductive coil 1 to form a first signal and sends the first signal to the data processing element 5.
