The ADXL345 Triple Axis Accelerometer Sensor Module measures acceleration along X, Y, and Z axes using the ADXL345 chip and outputs 16-bit two’s complement data. The triple axis accelerometer covers four selectable measurement ranges from plus or minus 2g up to 16g, making it usable for both low-vibration and high-impact sensing in the same project. It communicates over I2C or SPI, so you pick the interface that suits your wiring layout.
The adxl345 sensor resolution scales with the selected range, going from 10-bit at lower g settings up to 13-bit in high-resolution mode. A non-obvious detail is that at plus or minus 16g range the resolution per LSB (least significant bit) is fixed at approximately 3.9 mg, which may be too coarse for precision tilt measurement. The accelerometer sensor module runs on 3V to 6V, but its logic lines run at 3.3V internally.
Developers, and vibration monitoring engineers use the 3 axis accelerometer sensor. StemVolt provides sensors with trusted quality, ensuring reliable performance and easy usability.
