We've been using and selling Analog Devices' ADXL accelerometers for a good while now, and now we've found another great part in the series! The ADXL362 is a complete 3-axis acceleration measurement system that operates at extremely low power consumption levels. It measures both dynamic acceleration, resulting from motion or shock, and static acceleration, such as tilt. It's easy to communicate with the ADXL362 over SPI and built-in digital logic even enables autonomous operation for "wake-on-shake" operation.
