ADXL345

The ADXL345 is a small, thin, low-power, three-axis accelerometer with high-resolution (13-bit) measurement capability, designed by Analog Devices. It measures acceleration with a range of ±2 g, ±4 g, ±8 g, or ±16 g, making it suitable for various applications like device orientation, motion detection, and shock or vibration analysis.
Key features include a digital output accessible via I2C or SPI interfaces, which simplifies integration with microcontrollers and other digital systems. The ADXL345 also offers features like tap/double-tap detection, free-fall sensing, and activity/inactivity monitoring. Its low power consumption and sleep modes help conserve battery life in portable devices.
The sensor's high resolution makes it ideal for precise applications, while its small package size (3 mm x 5 mm x 1 mm) allows for integration in compact designs. These characteristics make the ADXL345 popular in consumer electronics, such as smartphones, wearables, and gaming devices, as well as in industrial and automotive applications.
