The MMA8452Q is a smart low-power, three-axis, capacitive MEMS accelerometer with 12 bits of resolution. With this breakout board, you can sense an object's orientation as well as if the object is in motion or in free-fall.

Description

Details

The MMA8452Q is a smart low-power, three-axis, capacitive micromachined accelerometer with 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user-programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data.

The MMA8452Q has user-selectable full scales of ±2g/±4g/±8g with high-pass filtered data as well as non-filtered data available real-time. The device can be configured to generate inertial wake-up interrupt signals from any combination of the configurable embedded functions allowing the MMA8452Q to monitor events and remain in a low-power mode during periods of inactivity.

Features:
  • 1.95 to 3.6-volt supply voltage
  • ±2g/±4g/±8g dynamically selectable full-scale
  • Output data rates (ODR) from 1.56 Hz to 800 Hz
  • 99 μg/√Hz noise
  • 12-bit and 8-bit digital output
  • I²C digital output interface (operates to 2.25 MHz with 4.7 kΩ pull-up)
  • Two programmable interrupt pins for six interrupt sources
  • Three embedded channels of motion detection
    • Freefall or motion detection: one channel
    • Pulse detection: one channel
    • Jolt detection: one channel
  • Orientation (portrait/landscape) detection with set hysteresis
  • Automatic ODR change for auto-wake and return to sleep
  • High pass filter data available real-time
  • Self test
  • Current consumption: 6 μA–165 μA
Target Applications:
  • eCompass applications
  • Static orientation detection (portrait/landscape, up/down, left/right, back/front position identification)
  • Notebook, eReader and laptop tumble and freefall detection
  • Real-time orientation detection (virtual reality and gaming 3-D user position feedback)
  • Real-time activity analysis (pedometer step counting, freefall drop detection for HDD, dead-reckoning GPS backup)
  • Motion detection for portable product power saving (auto-sleep and auto-wake for cell phone, PDA, GPS, gaming)
  • Shock and vibration monitoring (mechatronic compensation, shipping and warranty usage logging)
  • User interface (menu scrolling by orientation change, tap detection for button replacement
Documents and References: Note: The MMA8452Q IC expects a special type of START condition on the I2C bus, i.e., Repeated START. Since Raspberry Pi does not have this functionality inbuilt, we do not recommend this board for use with the Raspberry Pi. For more details, check this link.
