The Accel 5 Click Board™ features an ultra-low power triaxial accelerometer sensor, labelled as the BMA400. This Click Board™ allows linear motion and gravitational force measurements in ranges of ±2g, ±4g, ±8g, and ±16g in three perpendicular axes. Besides the acceleration measurement, the Accel 5 Click Board™ is able to output an interrupt for 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. However, a key feature of the BMA400 sensor is its extremely low power consumption.
