The ADXL345 is a popular and widely used digital accelerometer. It is a small, low-power, three-axis accelerometer that measures acceleration forces in three dimensions (X, Y, and Z).
The sensor is commonly used in various applications such as robotics, gaming, motion detection, and tilt sensing. It provides high-resolution measurement capabilities and can measure accelerations from ±2 g to ±16 g.
The ADXL345 communicates with other devices using I2C (Inter-Integrated Circuit) or SPI (Serial Peripheral Interface) protocols. It has a built-in 3-axis digital-to-analog converter that can provide raw acceleration data or perform onboard digital processing to calculate motion-related parameters like tilt, orientation, and tap detection.
Overall, the ADXL345 is a versatile accelerometer suitable for a wide range of applications requiring precise measurement of acceleration in multiple axes.
