Kionix KXTE9 series of 2g tri-axis digital accelerometers offer an advanced orientation-detection feature that reports changes in landscape, portrait, face-up, and face-down conditions. These Kionix accelerometers feature a sophisticated embedded algorithm that eliminates the need for continuous data collection and complex calculations by a microprocessor. With a few adjustable parameters, the screen-rotation algorithm can be optimized for an intuitive user experience. Kionix KXTE9 devices also feature an activity-monitoring function that reports changes in a device's motion state, either moving (active) or not moving (inactive). Kionix KXTE9 accelerometers operate across a supply voltage of 1.8V to 3.6V DC and are ideal for a variety of applications, including mobile phones, game controllers, and sports diagnostic equipment.
