Based on the excellent ADXL-345, this digital 3-axis accelerometer has excellent EMI protection. Its variable output makes it suitable for a wide range of applications: HDD shock protection Vibration sensor Game controller input Robotics Smart vehicles Anywhere you need to obtain motion-sensing & orientation information. The excellent sensitivity (3.9mg/LSB @2g) provids high-precision output up to ±16g. The sensor is utilizes a 4-pin Grove interface (3-5VDC) for easy connectivity with your standard Arduino device or Seeed Stalker. Features Wide power range DC3V to 5V Grove module 3 axis sensing High sensitivity Small, low-profile package: 14-Terminal LGA Low power 0.1 μA in standby mode at VS = 2.5 V (typical) 10,000 g shock survival RoHS/WEEE lead-free compliant For all Grove users (especially beginners), we provide you guidance PDF documents.
