What it does

The ADXL345 Triple Axis Digital Accelerometer Module is a low-power, high-resolution 3-axis MEMS accelerometer. It features selectable measurement ranges, both SPI and I2C interfaces, and built-in activity/inactivity detection for versatile motion sensing applications.

Key features

  • 3-axis acceleration sensing with selectable ±2g/±4g/±8g/±16g ranges
  • High 13-bit resolution at ±2g for precise measurements
  • Ultra-low power consumption as low as 23μA in measurement mode
  • I2C and SPI interfaces for flexible microcontroller integration
  • Tap and double-tap detection built into hardware
  • Activity/inactivity detection for power management
  • Free-fall detection capability for drop sensing

Good to know

  • Module includes voltage regulator for 5V input compatibility
  • Library available: Adafruit_ADXL345 or SparkFun_ADXL345
  • Calibrate zero-g offset for your application orientation
  • Higher data rates consume more power – balance as needed
  • SPI mode provides faster data rates than I2C
