GY-291 ADXL345 3-Axis Accelerometer Module for Arduino RPi ESP8266 etc

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 an SPI (3- or 4-wire) or I2C digital interface.

The ADXL345 is well suited to 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 degrees.

Several special sensing functions are provided. 

* Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. 
* Tap sensing detects single and double taps. 
* Free-fall sensing detects if the device is falling. 

These functions can be mapped to one of two interrupt output pins. An integrated, patent pending 32-level first in, first out (FIFO) buffer can be uséd to store data to minimise host processor intervention. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.
