LIS3DH - MEMS Motion Sensor
The LIS3DH is an ultra-low-power 3 axis linear accelerometer with an I2C serial interface for communication. It also has an additional SPI interface. The power draw can be as low as 2uA for the chip without any additional supporting circuitry. It is capable of measuring accelerations up to ±16g and can be configured to sense at ±2g/±4g/±8g/±16g depending on the use case. The LIS3DH also has 3 additional ADC inputs that can be read over I2C.
