Description

The ADXL345 is a low-power three-axis accelerometer designed for portable applications. It measures acceleration in the X, Y, and Z axes and is capable of detecting both static and dynamic acceleration, making it suitable for motion sensing, tilt detection, and gesture recognition.
Operating on a voltage range of 2.0V to 3.6V, the ADXL345 features a digital interface (I2C and SPI) for easy integration with microcontrollers and processors. It has a configurable measurement range of ±2g, ±4g, ±8g, or ±16g and provides a resolution of up to 13 bits, allowing for precise motion detection.
Additional features include a built-in tap and free-fall detection, a sleep mode for power conservation, and a high data rate up to 3200 Hz. Its compact size and low power consumption make it ideal for applications in smartphones, wearables, and other IoT devices, where efficient motion tracking is essential.
