Special Features

  • The BMA400 3 Axis Accelerometer 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.
  • Acceleration ranges +2g/+4g/+8g/+16g, Low-pass filter bandwidths=0.48*ODR, up to a max. output data read out of 800Hz
  • The continuous measurement principle and always-defined bandwidth, the BMA400 is the ideal solutionfor smart home applications such as smart indoor climate systems and smart home security systems. and the BMA4400 can distinguish between real alarm situations like broken glass and false signals coming from random vibrations.
