Digital acceleration module 

Outline: 

The ADXL345 is a small, thin, low-power 3-axis accelerometer, can high TAT ± 16 g acceleration measurement of the high resolution (13 bits).  

ADXL345 is well suited for mobile device applications.  

It can tilt-sensing applications .
Measuring the static acceleration of gravity can also measure the movement or shock lead dynamic plus Speed.  

It has a high resolution (4 mg / LSB), measuring approximately 0.25 ° tilting angle changes.  

The accelerometer ADXL345 digital output, without the need for The analog-to-digital conversion, which can save the system cost and board space.  

In addition, ADXL345 is a small, thin, ultra-low-power 3-axis accelerometer, resolution (13), the measurement range of ± 16g.
