Bosch Sensortec's BMA400 accelerometer SensorAPI

The BMA400 is the first real ultra-low power acceleration sensor that minimizes power consumption without compromising performance. Featuring 12-bit digital resolution, continuous measurement, and a defined selectable bandwidth combined with ultra-low power, the BMA400 allows low-noise measurement of accelerations in three perpendicular axes. Therefore, the BMA400 senses tilt, orientation, tab/double tab, and enables Plug and Play step counting with activity recognition especially suited for wearable devices that need a long-lasting battery lifetime.

Due to the continuous measurement principle and defined bandwidth, the BMA400 is the ideal solution for smart home applications such as smart indoor climate systems and smart home security systems. In the latter, the BMA400 can distinguish between real alarm situations (like broken glass) and false signals from random vibrations, thereby avoiding false alarms.

• IoT and smart home applications (e.g., indoor climate systems, security systems)
• Activity tracking and step counting in wearable devices (e.g., fitness bands, smart and regular watches, hearables)
• Industrial applications (e.g., predictive maintenance, package tracking)
• Power management of consumer end-devices based on motion
