Use this high performance acceleration sensor in your project to detect direction (transverse/longitudinal), as well as free fall, pulse, and shake detection. The on-board MMA8452Q is a smart low-power, three-axis, capacitive micromachine acceleration sensor with 12-bit resolution. Users are able to set a range of ±2g, ±4g, or ±8g, which can output high-pass filtering data and non-filtered data in real-time. An embedded function can also be used to generate an inertial wake-up interrupt signal, which enables MMA8452Q to maintain a low-power mode in the static state while monitoring the event.

Features:

• 12 bit and 8 bit digital outputs

• I2C digital output interface (up to 2.25MHz with 4.7k? pull-up resistor)

• Two programmable interruption pins applied to six interruption sources

• Three motion detection embedded channels: free fall detection, pulse detection, shaking detection

• Direction (transverse/longitudinal) detection with setting lag compensation

• Automatic arousal and auto-dormant ODR can be automatically altered

• High-pass filtering data can be exported in real time
