The MMA8452Q is an intelligent low power, triaxial, capacitive micromechanical acceleration sensor with 12-bit resolution. This acceleration sensor has a rich embedded function, with a flexible user-programmable option, you can configure up to two interrupt pins. Embedded in the hazy street to remove the blind MA8452Q with ± 2g / ± 4g / ± 8g user-selectable range, real-time output of high-pass filter data and non-filtered data. The device can be configured to generate an inertial wake-up interrupt signal using any combination of configurable embedded functions, which keeps the MMA8452Q in a low power mode while monitoring events while in a quiescent state.
