ADXL345 fast facts resolution, wide range for precise tilt and motion sensing The ADXL345 is a small, thin, ultralow power 3axis accelerometer with a 13bit resolution and a measurement range of ±16 g. Its resolution of 3.9 mg per LSB enables measurement of tilt angle changes of less than 1.0 degrees. Flexible digital output and easy integration Digital output data is provided in 16bit two's complement format. Data is accessible via SPI (3wire or 4wire) or I2C interfaces, allowing straightforward integration with a wide range of microcontrollers and development platforms. Ultralow power with intelligent power management The device supports a lowpower mode that enables motionbased intelligent power management. This mode covers threshold sensing and motion acceleration measurement with very low power consumption, helping extend battery life in portable applications. Compact form factor with reliable performance Designed as a compact, lightweight accelerometer suitable for portable and embedded applications. Combines precise angular sensing with robust motion data suitable for orientation, tilt monitoring, and motion analysis.
