LIS3DH Triple-Axis Accelerometer
The LIS3DSH is an ultra-low-power high-performance 3-axis linear accelerometer belonging to the “nano” family. It has dynamically user-selectable full scales of ±2g/±4g/±6g/±8g/±16g and is capable of measuring accelerations with output data rates from 3.125 Hz to 1.6 kHz. The self-test capability allows the user to check the functioning of the sensor in the final application. The LIS3DSH has an integrated first-in, first-out (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor. The device can be configured to generate interrupt signals activated by user-defined motion patterns. To do this, two embedded finite state machines can be programmed independently for motion detection. Each state machine has 16 states. It's low-cost, but has just about every 'extra' you'd want in an accelerometer.
