Introduction

This Triple Axis Accelerometer with Bosch BMA220 is an ultra small triaxial, low-g acceleration

sensor breakboard with 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 vibrati
