3-axis, ± 2g / ± 4g / ± 8g / ± 16g
Digital acceleration module
The ADXL345 is a small, thin, low-power 3-axis accelerometer, can high
TAT ± 16 g acceleration measurement of the high resolution (13 bits). Number of digital outputs
It is for the 16-bit two’s complement format
SPI (3-wire or 4-wire) or I2C digital interface.
ADXL345 is well suited for mobile device applications. It can tilt-sensing applications
Measuring the static acceleration of gravity can also measure the movement or shock lead dynamic plus
Speed. It has a high resolution (4 mg / LSB), measuring approximately 0.25 ° tilting
Angle changes. The accelerometer ADXL345 digital output, without the need for
The analog-to-digital conversion, which can save the system cost and board space. In addition,
ADXL345 is a small, thin, ultra-low-power 3-axis accelerometer, resolution
(13), the measurement range of ± 16g. The digital output data for the 16-bit binary
Complement format, via the SPI (3-wire or 4-wire) or I2C digital interface access.
ADXL345 is well suited for mobile device applications. It can be in tilt-sensing applications
To measure the static acceleration of gravity, can also measure the movement or shock lead dynamic
