Description: 1. Overview: The ADXL345 is a microelectromechanical systems (MEMS) triaxial accelerometer module from Analog Devices, capable of measuring acceleration in three dimensions with adjustable sensitivity. 2. Features: It offers a wide measurement range (-3 to +3 g), programmable output data rate up to 800 Hz, and low power consumption (as low as 1.5 mA). The module also includes built-in temperature sensors for self-calibration and an adjustable digital filter for smoothing the sensor output. 3. Communication: The ADXL345 communicates via a two-wire I²C or SPI interface, making it easy to connect to microcontrollers or other systems. It also supports single-ended and differential input modes with selectable full-scale ranges (±2 g, ±4 g, and ±8 g). 4. Applications: This versatile module is used in various IoT projects, such as robotics, wearables, fall detection sensors, vehicle motion detection systems, and environmental monitoring applications where measuring acceleration is essenti
