USPRO&reg; MMA8451 Digital Triaxial 3-axis Accelerometer Acceleration Module Precision Tilt for Arduino The MMA8451 is a smart low-power, three-axis, capacitive micro-machined 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 MMA8451 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 MMA8451 to monitor events and remain in a low power mode during periods of inactivity.
