Digital acceleration module
 
An overview of the
 
The ADXL345 is a compact, thin, low-power triaxial accelerometer that can be used for high power
Acceleration up to ±16 g for high resolution (13 bits) measurements. Digital output number
The data is in 16-bit binary complement format,
 
It can be accessed through SPI (3-wire or 4-wire) or I2C digital interface.
 
The ADXL345 is ideal for mobile applications. It can be used in tilt detection applications
Measure the static acceleration of gravity, but also measure the dynamic acceleration caused by motion or impact
Speed. It has high resolution (4 mg/LSB) and is capable of measuring a tilt of about 0.25°
Angle changes. Use ADXL345 and other digital output acceleration timing, no need to proceed
Analog-to-digital conversion, thus saving system cost and circuit board area. In addition,
 
 
The ADXL345 is a small and thin ultra-low power 3-axis accelerometer with resolution
High (13th digit), measuring range up to ± 16g. The digital output data is 16 bit binary
Complement format, accessible through SPI(3-wire or 4-wire) or I2C digital interface.
The ADXL345 is ideal for mobile applications. It can be applied in tilt detection
It can also measure the motion caused by motion or impact
State acceleration. Its high resolution (3.9mg/LSB) enables measurement of less than 1.0°
Tilt Angle changes.
The device provides a variety of special detection functions. Active and inactive detection function
Movement is detected by comparing the acceleration on any axis with the threshold set by the user
Still occur. Knock detection function can detect single and double vibration in any direction
Make it. The free fall detection function can detect whether the device is falling. these
Functionality can be independently mapped to one of two interrupt output pins. Is"
Patented integrated memory management system uses a 32 - class FIFO
(FIFO) buffer that can be used to store data and thus load the host processor
And reduce the overall system power consumption.
Low power mode supports smart power management based on motion, thus making it extremely low
Power consumption is measured by threshold sensing and motion acceleration.
ADXL345 adopts 3 mm × 5 mm × 1 mm, 14 pin small ultra-thin plastic
Encapsulation.
