Overview

Le Magneto 7 Click Board™ est un capteur magnétique haute résolution Click Board™ qui permet une détection d'orientation sans contact. Il comprend le BM1422AGMV, une solution intégrée complète avec des éléments à magnéto-impédance (MI), un convertisseur analogique-numérique à faible bruit et des sections de traitement du signal numérique (DSP), sur la même matrice.

Grâce au traitement DSP interne, le BM1422AGMV peut transmettre la détection de mouvement absolue via l'interface série sous forme de flux binaire. Le circuit intégré BM1422AGMV est idéal pour une utilisation dans diverses applications, telles que les montres-bracelets, les smartphones, les tablettes, etc.

The Magneto 7 Click Board™ is a very accurate and reliable magnetic sensor device, which features the BM1422AGMV, a 3-axis magnetic sensor IC from ROHM Semiconductor. The BM1422AGMV IC features an onboard signal processing and I2C communication, simplifying the application development and reducing the host MCU load. It is a very accurate sensor, which can sense the magnetic field with the precision of 0.042μT, with the full scale magnetic field detection of ±1200μT. Featuring onboard signal processing, fast I2C communication, low power consumption, and high precision with the low noise, this Click board™ is an ideal solution for developing portable electronic compass applications, but it is not limited only to directional measurement. It can be also used for the detection of a magnetic field, vehicle detection, and similar applications that rely on an accurate magnetic field sensing in all three axes.

How Does The Magneto 7 Click Board™ Work?

The Magneto 7 Click Board™ uses the BM1422AGMV, a 3-axis magnetic sensor IC from ROHM Semiconductor. This sensor incorporates magneto-impedance (MI) elements to detect magnetic field and a control IC in a small 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 orientation of the user, and therefore simplify the development of motion tracking applications.

The resulting characteristics of this sensor IC, are impressive: it have measurable range of ±1200μT, a sensitivity of 0.042μT/LSB when using 14 bit ADC mode, and can be exposed to maximum 1000mT field. The Status register offers the status indication of the measured data. This, DRDY bit, is output to inform the preparation status of the measured data and is routed to the INT pin of the Click board™.

The Magneto 7 Click Board™ uses I2C, and it is designed to be operated only with 3.3V logic level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 5V.
