3.5.7 BMA253 Acceleration Sensor

The Bosch BMA253 is a low-g acceleration sensor with digital output for measurements of acceleration in three perpendicular axes.

Additional Features:
  • 12-Bit Sensitivity
  • User Selectable Acceleration Ranges: ±2g, ±4g, ±8g, ±16g
  • On-Chip 32 Frame First-In First-Out (FIFO)
  • Motion Triggered Interrupts:
    • New Data
    • Any Motion Detection
    • Single/Double Tap Sensing
    • Orientation Recognition
    • Flat Detection
    • Low/High-g Detection
    • Inactivity Detection
  • Operating Voltage Range: 1.62V to 3.6V
  • Operating Current (Normal mode): 130 μA (typical)
  • Shutdown Current (Deep Suspend mode): 1 μA (typical)
The BMA253 acceleration sensor is connected to the ATmega3208 through I2C and two GPIOs for the user configurable interrupt outputs.
Info: 7-bit I2C address: 0x19
