Digital acceleration module
summary
The ADXL345 is a small and thin three-axis accelerometer with low power consumption, which can
The acceleration up to ± 16 g is measured with high resolution (13 bits). Number of digital outputs
According to the 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 device applications. It can be used in tilt detection applications
Measure static gravity acceleration, and also measure dynamic acceleration caused by motion or impact
Speed. It has high resolution (4 mg/LSB) and can measure the inclination of about 0.25 °
Angular variation. Digital output accelerometers such as ADXL345 can be used without
A/D conversion can save system cost and circuit board area. In addition,
The ADXL345 is a small and thin 3-axis accelerometer with ultra-low power consumption and resolution
High (13 bits), measuring range of ± 16g. The digital output data is 16 bit binary
Complement format can be accessed through SPI (3-wire or 4-wire) or I2C digital interface.
The ADXL345 is ideal for mobile device applications. It can be used in tilt detection
The static gravity acceleration can be measured in, and the motion caused by motion or impact can also be measured
State acceleration. Its high resolution (3.9mg/LSB) can measure
Tilt angle change.
The device provides a variety of special detection functions. Active and inactive detection functions
Check whether there is operation by comparing the acceleration on any axis with the threshold set by the user
Actiogenesis. Knock detection function can detect single vibration and double vibration in any direction
Do. The free fall detection function can detect whether the device is falling. these
Functions can be independently mapped to one of the two interrupt output pins. Applying
The patented integrated memory management system adopts a 32 level FIFO
(FIFO) buffer, which can be used to store data to load the host processor
Minimize and reduce overall system power consumption.
Low power consumption mode supports intelligent power management based on movement, so as to
Power consumption for threshold sensing and motion acceleration measurement.
