Description of Grove 3 Axis Digital Accelerometer ±16g The Grove 3-Axis Digital Accelerometer ±16g is a small, thin, ultra-low power accelerometer module based on the ADXL-345 sensor. It provides high-resolution (13-bit) measurement at up to ±16g and can measure both static acceleration for tilt sensing and dynamic acceleration from motion or shock. With robust EMI protection and multiple sensing capabilities, it is ideal for a wide range of applications, including robotics, gaming, industrial automation, and smart vehicles. Key Features Based on ADXL-345 Sensor: High-precision motion detection and orientation sensing. Excellent EMI Protection: Ensures stable operation in high-interference environments. 3-Axis Sensing: Supports activity/inactivity sensing, tap sensing, and freefall detection. Ultra-Low Power Consumption: As low as 23μA in measurement mode and 0.1μA in standby mode. Wide Measurement Range: Supports acceleration measurements up to ±16g. High Sensitivity: 3.9mg/LSB @2g, enabling inclination changes of less than 1.0°. Strong Shock Resistance: Can withstand up to 10,000g shock survival. Multiple Interface Options: Compatible with I2C and SPI communication protocols. Easy Connectivity: Utilizes a 4-pin Grove interface (3-5VDC) for seamless integration with Arduino and Seeed Stalker.
