Mikroe MIKROE-3657 Magneto 7 Click
Mikroe MIKROE-3657 Magneto 7 Click is a high-resolution magnetic sensor Click board that allows contactless orientation sensing. The Mikroe Magneto 7 Click features the ROHM Semiconductor BM1422AGMV, a complete integrated solution with magneto-impedance (MI) elements, low-noise analog AD converter, and digital signal processing (DSP) sections in one compact package. The BM1422AGMV can sense the magnetic field with the precision of 0.042μT, with the full-scale magnetic field detection of ±1200μT.
The BM1422AGMV combines magneto-impedance (MI) elements and a control IC in a single package. The magneto-impedance (MI) effect is a phenomenon in which the voltage induced by a high-frequency current source in a ferromagnetic wire changes with the application of an external field. Just like a global positioning system (GPS) is effective for detecting the position, a magnetic sensor is usable for detecting the user's orientation and simplifies the development of motion-tracking applications.
