LIS3DH Triple Axis Accelerometer

The LIS3DH triple-axis accelerometer.

• Three axis sensing
• ±2g/±4g/±8g/±16g selectable scaling
• Both I2C (2 possible addresses) and SPI interface options
• Interrupt output
• Multiple data rate options 1 Hz to 5Khz
• As low as 2uA current draw (just the chip itself, not including any supporting circuitry)
• Tap, Double-tap, orientation & freefall detection
• 3 additional ADC inputs you can read over I2C

This sensor communicates over I2C or SPI (Adafruit library code supports both) so you can share it with a bunch of other sensors on the same I2C bus. There's an address selection pin so you can have two accelerometers share an I2C bus.

The input voltage is 3.3V, you can use a level shifter on the I2C pins.
