ADXL345

The ADXL345 is a compact, low-power, 3-axis digital accelerometer with high resolution (13-bit) measurement capabilities up to ±16g. This versatile sensor is ideal for measuring both static acceleration, such as gravity, and dynamic acceleration from motion or vibration. Equipped with flexible I2C and SPI communication interfaces, the ADXL345 is widely used in mobile devices, gaming, industrial instrumentation, and DIY electronics projects like Arduino and Raspberry Pi-based motion sensing applications.

Features:

• High-resolution 13-bit measurement across X, Y, and Z axes

• Selectable measurement ranges: ±2g, ±4g, ±8g, and ±16g

• Supports I2C (up to 400 kHz) and SPI (3- or 4-wire) digital communication

• Built-in activity and inactivity detection, tap and double-tap sensing, and free-fall detection

• Integrated 32-level FIFO buffer for efficient data handling

• Ultra-low power consumption: 23μA in measurement mode, 0.1μA in standby

• Operates over a wide temperature range from -40°C to +85°C

• Small and thin form factor: 3 mm × 5 mm × 1 mm, LGA package
