Bosch Sensortec's BMA400 is the first real ultra-low power acceleration sensor without compromising on 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. The BMA400 thus senses tilt, orientation, tab/double tab, and enables plug ’n’ play step counting with activity recognition especially suited for wearable devices, which need a long-lasting battery lifetime. Thanks to the continuous measurement principle and always-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 coming from random vibrations. Thereby, the new acceleration sensor avoids false alarms.

The Bosch Sensortec BMA400 shuttle-board is a PCB with a BMA400 sensor mounted on it. It allows easy access to the sensor's pins via a simple socket. Since all Bosch Sensortec sensor shuttle boards have an identical footprint, they can be plugged into Bosch Sensortec’s advanced development tools (e.g. the development board). The BMA400 shuttle board can also be used for the user's own implementations as well.
