Measuring acceleration and tilt
The voltage outputs on the DE-ACCM6G correspond to acceleration being experienced in the X and Y
directions. The output is ratiometric, so the output sensitivity (in mV/g) will depend on the supply voltage.
Sensitivity is typically 222mV/g. Zero acceleration (0g) will result in an output of Vcc/2 regardless of the
voltage supplied to the unit.
Due to manufacturing variances when ST Microelectronics makes their accelerometer chips, these values
aren’t always set in stone. They can vary by up to 4% in extreme cases, including the 0g bias point. For
projects that require a very high degree of accuracy, we recommend that you incorporate measured
calibrations into your hardware/software.
