La carte Click Board™ Magneto 11 est une carte complémentaire compacte qui contient un dispositif de détection magnétique précis et fiable. Cette carte est équipée de l'AS5510, un capteur à effet Hall linéaire avec une résolution de 10 bits et une interface I2C d'AMS AG. Elle peut mesurer la position absolue du mouvement latéral d'un simple aimant à 2 pôles. Une course latérale de 0,5 mm à 2 mm peut être mesurée avec des entrefers d'environ 1,0 mm, selon la taille de l'aimant. L'AS5510 peut être mis en mode hors tension lorsqu'il n'est pas utilisé pour économiser de l'énergie. Cette carte Click Board™ convient aux applications de détection de position nécessitant une petite plage magnétique où le bruit est un paramètre de conception critique.
La carte Click Board™ Magneto 11 est supportée par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does The Magneto 11 Click Board™ Work?
The Magneto 11 Click Board™ as its foundation uses the AS5510, a 10-bit linear position sensor with digital position (interface) output from AMS AG. The AS5510 can measure the absolute position of lateral movement in combination with a diametrical two-pole magnet. The sensor needs a simple 2-pole magnet to measure a lateral movement, and the measured distance depends on the magnet geometry. A lateral stroke of 0.5mm ~ 2mm can be measured with air gaps around 1.0mm, depending on the magnet size. With stronger magnets, even higher lateral strokes and air gaps are possible.
The AS5510 comes in a version of a ±50mT full-scale sensing range to deliver the highest reliability and durability in contactless position measurements. By selecting different measurement ranges, it is possible to choose different sensitivity values; the default sensitivity value of the AS5510 is 97.66µT/LSB. It also features a Power-Down mode that helps save energy and maximize run-time in battery-powered applications.
The Magneto 11 Click Board™ communicates with MCU using the standard I2C 2-Wire interface for switching between four different sensitivity ranges and for simple data transmission to an MCU, supporting Fast Mode Plus operation with a clock frequency up to 1MHz. The absolute position is measured with a resolution of 10 bit = 1024 positions, and it is provided as a digital value on the serial interface. Besides, the AS5510 allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labelled ADDR SEL. The selection can be made by positioning the SMD jumper to an appropriate position marked as 1 or 0.
The Magneto 11 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
