The ADXL345 is a compact, versatile 3-axis accelerometer designed to measure acceleration in multiple ranges with high accuracy. It is widely used in applications such as device orientation, motion detection, vibration monitoring, and gaming controls. Due to its lightweight design and low power consumption, the ADXL345 is ideal for portable and battery-operated devices. The module supports I2C and SPI communication protocols, making integrating with various microcontrollers like the 51 series, AVR, and Arduino easy.

Features

• High Precision: Measures acceleration across three axes (X, Y, Z) with selectable ranges from ±2g to ±16g.
• Dual Communication Protocols: Supports both I2C and SPI for flexible interfacing options.
• Low Power Consumption: Optimized for battery-operated applications.
• User-Selectable Ranges: Provides a choice of four measurement ranges: ±2g, ±4g, ±8g, and ±16g, enabling customization for different applications.
• High Resolution: Capable of detecting small changes in tilt and movement, suitable for applications requiring high precision.
• Embedded FIFO Buffer: Stores data to reduce the workload on the host processor.
• Free-Fall Detection: Built-in functionality to detect free-fall conditions, ideal for protective or emergency applications.
