3-Axis Digital Accelerometer Unit (ADXL345)

This accelerometer unit is a motion sensor unit. Integrated with ADXL 345 and ACC, it is able to obtain a 3-axis of acceleration. The ADXL 345 is a small, thin, ultra-low power consumption 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement, and it is accessible through I2C (addr:0x53) digital interface. In this unit, we used the I2C series interface.

Features

• Ultra-low power consumption
• Single tap/double tap detection
• Activity/inactivity monitoring
• Free-fall detection
• I2C digital interface
• Wide temperature range
