Adxl345 digital three-axis acceleration of gravity tilt module

ADXL345 Digital 3-axis Acceleration, Gravity, Tilt sensor module – GY-291


The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.
The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0°.
Applications:
    Gesture Sensing
    Tap/Double Tap Detection
    Free-Fall Detection
    Impact or colision Detection
    Accident Detection
