The Accel 11 Click Board™ features an ultra-low power triaxial accelerometer sensor with embedded intelligence, labelled as the BMA456. This Click Board™ allows linear motion and gravitational force measurements in ranges of ±2 g, ±4 g, ±8, and ±16 g in three perpendicular axes.
This smart sensor allows the Accel 11 Click Board™ to detect many different events, including tap, double-tap, step counting, activity recognition (walk, run, stand still), activity change (any type of acceleration pattern change), orientation, and more. It features onboard data processing, offering the acceleration data directly, over the standard I2C or SPI interface.
