The 3-axis acceleration sensor family is specifically designed for low-power applications to enhance functionality in smartphones and consumer electronic devices. All accelerometers are available in small and thin LGA packages. The interrupt feature of the sensors offers an additional special advantage for mobile applications such as a battery saving mode or free-fall detection. The sensing principle of all listed MEMS sensors is capacitive detection.
