ADXL345 3Axis Accelerometer

Description :

The ADXL345 is a popular triple-axis accelerometer sensor developed by Analog Devices. It's commonly used in various applications to measure acceleration along three perpendicular axes. Here's an overview of the ADXL345 accelerometer:

The ADXL345 is a MEMS (Micro-Electro-Mechanical Systems) accelerometer, meaning it uses microfabrication techniques to create extremely small mechanical devices on a silicon wafer.

It measures acceleration by detecting changes in capacitance caused by the movement of a small, internal mass.

Key Features :

• Triple-Axis Acceleration: Measures acceleration in the x, y, and z axes.
• Digital Output: Provides digital output through I2C or SPI communication protocols.
• Selectable Ranges: Can be configured to measure acceleration within different ranges (±2g, ±4g, ±8g, ±16g).
• High Resolution: Offers high resolution with up to 13-bit measurement data.

Pin Configuration :

1. VCC: Power supply (typically 3.3V or 5V).
2. GND: Ground.
3. CS (Chip Select): SPI chip select input (used in SPI mode).
4. SDO/ALT ADDRESS: SPI data output or alternate I2C address select.
5. SDA/SDI/SDIO: I2C data input or SPI data input/output.
6. SCL/SCLK: I2C clock input or SPI clock input.

Communication Protocols :

The ADXL345 can communicate using either I2C or SPI. The communication protocol is selected by setting the appropriate pins on the device.
