Application note

Tilt measurement using a low-g 3-axis accelerometer

Introduction
This application note describes the methods and techniques for measuring tilt angles from a
low-g 3-axis accelerometer. The LIS331DLH 3-axis digital accelerometer is used as an
example in this document. Other 3-axis analog or digital accelerometers may also be
applied to the tilt angle measurement procedures described here, depending on their
respective specifications.
The ultra-low power LIS331DLH digital accelerometer is housed in a 3 x 3
