Tilt-sensing with Kionix MEMS accelerometers

Posted: 19 Oct 2009 ?? ?Print Version ?Bookmark and Share

Keywords:MEMS Kionix? accelerometers tilt sensing? guidelines accelerometer?

Tilt/inclination sensing is a common application for low-g accelerometers. This application note describes how to use Kionix MEMS low-g accelerometers to enable tilt sensing. Applicable theory, plots and equations are provided with this note as guidelines.

Accelerometers have countless potential tilt-sense applications in today's motion-enabled world. Tilt-sensing opportunities exist in a variety of industries, such as automotive, consumer electronics and military/aerospace, and include: vehicle stability systems; inclinometers; cell phone/PDA screen navigation; motion-enabled game play; tilt-enabled computer mouse/pointer; and tilt-compensated electronic compass.

Some of these applications currently use dual-axis accelerometers that, at times, are adequate for the job. A tri-axis accelerometer, however, can enable additional functionality, accuracy and precision.
