ADXL362!

The ADXL362 is Analog Devices ultralow power, 3-axis MEMS accelerometer that consumes less than 2 A at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. In addition to its ultralow power consumption, the ADXL362 has many features to enable true system level power reduction. In the absence of motion, the ADXL362 enters sleep mode at which time the iPhone/iPad updates to reflect the change in state.
