Grove - 3-Axis Digital AccelerometerThis digital 3 axis accelerometer has excellent EMI protection. Its variable output makes it suitable for a wide range of applications like: vibration sensor, game controller input, or robotics. Anywhere you need to obtain motion sensing & orientation information. The excellent sensitivity (3. 9mg LSB @2g) provide high precision output up to 16g. The sensor utilises a 4 pin Grove interface (3 5VDC) for easy connectivity with your standard Arduino
