Smart sensors track fitness activity
STMicroelectronics’ LIS2DS12 3-axis accelerometer, LSM6DSL/M 6-axis inertial module, and new LSM303AH eCompass enable always-on fitness-tracking applications to operate longer and record progress more accurately. by Susan Nordyk @ edn.com:
These smart sensors help track movement continuously with minimal impact on device battery life by performing various motion-related calculations on-chip, instead of using the main system processor.
