Digital acceleration module

Summary

ADXL345 is a compact and slim low power three axis accelerometer, on high

Acceleration of + 16 g is performed with high resolution (13 bit) measurements. Digital output

It is a 16 bit binary complement format,

Access via SPI (3 line or 4 line) or I2C digital interface.

ADXL345 is ideal for mobile device applications. It can be used in tilt detection applications

Measure the static gravity acceleration, and also measure the dynamic addition caused by motion or impact

Speed. It has a high resolution (4 mg/LSB) and is capable of measuring about 0.25 degrees of inclination

Angular variation. The use of ADXL345 and other digital output acceleration timing, without the need to proceed

Analog to digital conversion, which can save system cost and circuit board area. Besides,

ADXL345 is a small, thin, ultra low power, 3 axis accelerometer with resolution

High (13 bit), measuring range of + 16g. The digital output data is 16 bit binary

The complement format can be accessed via SPI (3 line or 4 line) or I2C digital interface.

ADXL345 is ideal for mobile device applications. It can be applied in tilt detection

Measure the static gravity acceleration, and also measure the movements caused by motion or shock

State acceleration. Its high resolution (3.9mg/LSB) can measure less than 1 degrees

Tilt angle change.

The device offers a variety of special detection functions. Active and inactive detection function

Compare the acceleration on the arbitrary axis with the threshold set by the user to check if there is any movement

Occur. The knock detection function can detect single vibration and double vibration in any direction

For. The free fall detection function detects whether the device is dropping. These ones here

The function can be mapped independently to one of the two interrupt output pins. Shen Shen

The patented integrated memory management system employs a 32 stage FIFO

(FIFO) buffers can be used to store data and thereby load host processors

Minimizes and reduces overall system power dissipation.

Low power mode supports motion based smart power management, resulting in extremely low power

Power consumption is measured by threshold sensing and motion acceleration measurements.

The ADXL345 uses 3 mm x 5 mm x 1 mm, 14 lead Mini slim plastic

Encapsulation.
