3-Axis acceleration sensor measures the acceleration of an object in motion. It could help you to analyse the target motion position or direction. The typical interactive application could be the posture recognition and action recognition, such as WII game applications. These video game devices use internal acceleration sensors, calculating the current motion direction by conversion algorithms. The most recent smart devices are now using the same theory, like Misfit, Microsoft band .etc.
FXLN83XXQR1 series is a high precision 3-Axis acceleration sensor with low power consumption. The highest bandwidth being 2.7kHz with an analog output compatible with most MCU. It is well suited to measuring the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock.
The new FXLN8361 accelerometer sensor provides two measurement range: ±2g/±8g. You could select your range according to your application.
