Bosch Sensortec's BMA456 digital, triaxial, low-gl acceleration sensor with digital interface for low-power consumer applications Bosch Sensortec's BMA456 is an ultra-small, triaxial, low-g, high-performance acceleration sensor with digital interface, designed for low-power and demanding consumer electronics applications.
Featuring 16-bit digital resolution and embedded intelligence, the BMA456 allows low-noise measurement of accelerations in three perpendicular axes and thus senses wrist tilt, tap/double tap, and enables plug-and-play step counting especially in wearable devices. The superior temperature behavior of BMA456 facilitates accurate measurements over changing temperature. The reduced height of only 0.65 mm is beneficial for wearable devices.
