Acceleration sensor: BMA400
Ultra-low power. Battery lifetime enhancement.
BMA400
Accelerometer
Bosch Sensortec´s triaxial BMA400 is the first real ultra-low power acceleration sensor. Accordingly, the BMA400 is especially suited for wearable devices, which need a long-lasting battery lifetime. Further, it is the ideal solution for smart home applications e.g. smart indoor climate systems and smart home security systems. By distinguishing between critical situations and false signals, the new acceleration sensor avoids false alarms.
