MMA8452Q is a smart low-power 12-bit resolution, three-axis, capacitive micromachined acceleration sensor. 

This acceleration sensor with rich embedded functions with flexible user-programmable options, you can configure up to two interrupt pin. Embedded interrupt functions can save the overall power consumption, and to relieve the main processor constantly polling data burden. 

MMA8452Q has ± 2g / ± 4g / ± 8g of user-selectable range, the output of the high-pass filter data and non-filtered data in real-time. 

The device can be configured to use any combination of the configurable embedded functions generate inertial wake-up interrupt signal, which makes the MMA8452Q to monitor events at the same time, to maintain a low-power mode in the stationary state.
