Overview

Adxl 345 is a compact, thin, low power consumption triaxial accelerometer, which can be used for high
Acceleration up to 16 g is measured at a high resolution (13-bit).Digital output
According to the 16 bit binary code format,

Access can be made through spi (3 or 4 lines) or i2c digital interfaces.

Adxl 345 is very suitable for mobile device applications.It can be used in tilt detection applications
Measurement of static gravity acceleration and dynamic addition resulting from motion or impact
Speed.It has a high resolution (4 mg/lsb) capable of measuring about 0.25°Of the
Angle change.No need to use adxl 345 digital output accelerometers
Mode conversion can save system cost and circuit board area.In addition,


Adxl 345 is a small, thin, ultra-low power consumption 3 axis accelerometer with a resolution
High (13-bit), measuring 16g.Digital output data are 16 bits binary
Fill-in format, accessible through spi (3 or 4 lines) or i2c digital interface.
Adxl 345 is very suitable for mobile device applications.It can be applied in tilt detection
The static acceleration of gravity can also be measured by motion or impact.
State acceleration.Its high resolution (3.9 mg/lsb) can be measured less than 1.0°Of which
Change in tilt angle.
The device provides a variety of special detection functions.General function of activity and inactive detection
Compare accelerations on any axis with user-set thresholds to detect movement
It's moving.Percussion detection function can detect single and double vibrations in any direction
Done.The free drop detection function can detect whether the device is falling.These
The function can be mapped independently to one of two interrupt output pins.Under application
Request patent integrated memory management system to adopt a level 32 advanced first-come first-served
(fifo) buffers that can be used to store data, thereby loading mainframe processors
To minimize and reduce power consumption of the system as a whole.
Low power consumption mode supports motion-based intelligent power supply management, which is very low
Power consumption is measured by threshold sensing and motion acceleration.
