Electrobot GY-291 ADXL345 3-Axis ±2/4/8/16g Digital Acceleration Sensor Module IIC/SPI Interface Electronic Components Electronic Hobby Kit

The ADXL345 is a small, thin, low power, three-axis accelerometer with high resolution (13-bit) measurement up to ±16 g. Digital output data is formatted as 16-bit two complement and is accessible through either a SPI (3- or 4- wire) or I²C digital interface. The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4mg/LSB) enables resolution of inclination changes of as little as 0.25°. Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-Fall sensing detects if the device is falling. These functions can be mapped to interrupt output pins. Applications: * Handsets * Gaming and pointing devices * Personal navigation devices * HDD protection * Fitness equipment * Digital cameras
