Fermion - 3-Axis Accelerometer - I2C LIS2DW12 - DFRobot SEN0405

Fermion series module with powerful 3-axis accelerometer LIS2DW12, manufactured by DFRobot. It features low power consumption (50nA), as well as low noise. The module has a user-selectable measurement scale (±2 g / ±4 g / ±8 g / ±16 g) and is able to measure accelerations with a data rate of 1.6 Hz to 1.6 kHz. It communicates over an I2C interface and is powered by 3.3 V . The sensor features two independent programmable interrupt outputs and internal circuitry for motion and acceleration detection, free-fall detection and orientation determination, as well as single / double touch recognition.
