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.


  • Ultra-low power consumption
  • Single tap/double tap detection
