ACCELEROMETRO 3 ASSI – BMA220 - SEN0168

ACCELEROMETRO 3 ASSI – BMA220

TRIPLE AXIS ACCELEROMETER - BMA220

Questo accelerometro a 3 assi, basato sul chip BOSH BMA 220 è un piccolissimo tre assi, con un sensore a bassa g accelerazione con un interfaccia I2C, ideale per il mercato consumer.

Esso consente la misurazione delle accelerazioni nei 3 assi perpendicolari e rileva quindi: inclinazione, movimento, urti e vibrazioni nei telefoni cellulari, palmari, periferiche per computer, interfacce uomo-macchina e tutte le applicazioni che necessitano di un preciso controllo.

Con le sue ridottissime dimensioni e peso, il BOSH BMA220 rappresenta una nuova generazione di accelerometri.

ATTENZIONE: Si raccomanda di collegare il sensore all’uscita 3,3v dell’alimentazione del microcontrollore, Benchè possa lavorare con  Arduino UNO/Leonardo (System working voltage: 5v). 

INTRODUCTION

This Triple Axis Accelerometer with Bosch BMA220 is an ultra small triaxial, low-g acceleration sensor breakboard with SPI and I2C interface, aiming for lowpower consumer market applications. It allows measurement of accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers.

With a size of only 2 mm x 2 mm, the Bosch BMA220 represents a new generation of acceleration sensors. The Tri-Axis Accelerometer integrates a multitude of features that acilitates its use especially in the area of motion detection applications, such as device orientation detection, gaming, HMI and menu browser control. It is highly configurable in order to give the designer full flexibility when integrating the sensor into his system.

It can be used in sensing tilt, motion and shock vibration in mobile devices, handhelds, digital peripherals, man-machine interfaces, virtual reality features and game consoles.

Note: Recommend to connect the sensor to 3.3v powered microcontroller. Though it directly works with Arduino UNO/Leonardo(System working voltage: 5v).
