Tilt measurement using?a?low-g 3-axis accelerometer

Posted: 11 May 2010 ?? ?Print Version ?Bookmark and Share

Keywords:3-axis accelerometer? tilt measurement? low-g accelerometer?

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 3mm x 3mm x 1mm LGA-16 package. It has an I?C/SPI digital serial interface for 3-axis acceleration outputs, so no external ADC chip is required. It also features a dynamically user-selectable full-scale measurement range of 2g/4g/8g, with output data rates from 0.5Hz to 1kHz.
