Description

BMA140 Triaxial Analog Acceleration Sensor

Product Overview

The BMA140 is a fully calibrated, triaxial low-g analog acceleration sensor designed for consumer market applications. It measures static and dynamic accelerations along three perpendicular axes, enabling absolute orientation detection in a gravity field and free-fall detection. This compact sensor module is built upon Bosch's automotive-proven MEMS wafer-fabrication technology, offering ultra-low power consumption and a fast wake-up time. It is ideal for tilt, motion, and vibration sensing in a wide range of applications including gaming, virtual reality, wearables, mobile devices, PDAs, navigation systems, and computer peripherals.
