REUTLINGEN, Germany, Nov. 7, 2018 — 
The BMA400 ultra-low-power micro-electromechanical systems (MEMS) acceleration sensor from Bosch Sensortec GmbH is designed for Internet of Things and wearable applications.
With low current consumption, embedded plug-and-play step counting, and activity recognition features, the BMA400 substantially extends battery lifetime of wearables such as smart watches and fitness trackers. It can wake up automatically when it detects motion and returns to sleep mode when the movement ends, thus avoiding waking the main application processor. With its built-in voltage regulator, the BMA400 delivers stable performance over a wide supply voltage range. It offers flexible device tuning for power consumption, noise, and output data rate parameters. The BMA400 has a current consumption of 14 µA at highest performance, continuous measurement, and a noise density of 180 µg/vHz.
For Internet of Things (IoT) applications like indoor climate systems and security systems in smart homes, the BMA400’s continuous measurement capabilities and always-defined bandwidth make it an ideal choice for hassle-free usage.
