Chip selection
Depending on the type of architecture, the user has to select either an analog or digital
MEMS device. After, depending on the precision needed, the user will choose either the
LIS344ALH or LIS3LV02DL, if small-angle detection is required. If such a level of precision
is not needed, one can use the LIS302SG or LIS302DL. If the z axis is not affected (the
device is supposed to tilt around the z axis), a 2-axis accelerometer could be used.
Example 1
In the case of the LIS3LV02DL, the resolution is 1 mg per lsb. Thus, for an acceleration
variation of 1 mg, the angle measured on the z axis will be cos
axis, the angle detection will be sin
measurable is therefore 0.057°. This difference between the x and z axis is explained by the
behavior of the sine/cosine function.
Example 2
In the case of the LIS344ALH, the resolution is given by the formula [noise
density*rt(BW*correction factor)]. BW is the bandwidth and the correction factor is linked to
the low-pass filtering for the V
variation of 0.625 mg, the angle detection on the z axis will be cos
the x axis, the angle detection will be sin
Example 3
In the case of the LIS302DL, the resolution is 18 mg per lsb. Thus, for an acceleration
variation of 18 mg, the angle measured on the z axis will be cos
axis, the angle detection will be sin
Example 4
For the LIS302SG the resolution is 2.5 mg. Thus, the smallest angle variation measurable is
0.14°.
Due to the behavior of the sine/cosine functions and the angle and precision expected, the
user will have to consider the measured acceleration on one or all axes.
