Overview
The ADXL345 is a compact 3-axis digital accelerometer from Analog Devices. It measures acceleration on the X, Y, and Z axes and sends the data out over a digital interface for easy use with microcontrollers and embedded systems. Engineers commonly use it when they need motion, tilt, tap, or simple vibration sensing in a small package.
Why Choose This Part
The ADXL345 is attractive when you want a proven digital accelerometer with straightforward MCU interfacing and a small board footprint. Its digital output reduces analog front-end design work and makes prototyping faster on common embedded platforms. It is also widely supported in example code and breakout-board ecosystems, which lowers integration effort.
Applications
Getting Started
For quick prototyping, use an ADXL345 breakout board with a 3.3 V microcontroller such as an Arduino-compatible board, ESP32 board, or Raspberry Pi. Most integrations use I2C or SPI, so start with a vendor or community library for your target platform and verify the sensor orientation and full-scale settings in software. For production designs, follow the Analog Devices datasheet for decoupling, layout, and interface-voltage requirements before freezing the PCB.
