Outline

The ADXL345 is a small, thin , low -power three-axis accelerometer , can be high
Up to ± 16 g acceleration with high resolution ( 13 ) measurements. Digital Outputs
According to 16-bit two's complement format ,

Or I2C digital interface can be accessed through the SPI (3 -wire or 4-wire ).

ADXL345 is well suited for mobile device applications . It can tilt sensing applications
Measuring the static acceleration of gravity , you can also measure the dynamic increase resulting from motion or shock
Speed. It has a high resolution (4 mg / LSB), capable of measuring the tilt of about 0.25 °
Angle change . Use the accelerometer ADXL345 digital output , etc. , without the need for
Analog to digital conversion, thus saving system cost and board area . In addition,

The ADXL345 is a small, thin, ultra-low -power 3-axis accelerometer , resolution
High ( 13 ) , measuring range up to ± 16g. The digital output data is 16 -bit binary
Complement format , or I2C digital interface can be accessed through the SPI (3 -wire or 4-wire ) .
ADXL345 is well suited for mobile device applications . It can tilt sensing applications
Measuring the static acceleration of gravity , can also measure the impact caused by movement or action
State acceleration. Its high resolution (3.9mg/LSB), capable of measuring less than 1.0 °
The inclination angle .
The device offers a variety of special detection. Active and inactive detection through
Comparing arbitrary axis acceleration threshold set by the user to detect the presence of transport
Action to occur. Tapping any direction detection function can detect single and dual vibration vibration
Made . Freefall detection function can detect whether the device is dropped . These
Function can be independently mapped to two interrupt output pin one . Being Shen
Please patented integrated memory management system uses a 32 FIFO
(FIFO) buffer can be used to store data to the host processor load
Minimize and reduce overall system power consumption.
Motion -based low-power mode supports intelligent power management, which at very low
Power consumption threshold sensing and active acceleration measurement .
ADXL345 uses 3 mm × 5 mm × 1 mm, 14 -pin mini ultra-thin plastic
