ADXL345 is a small accelerometer with low power consumption and with 13-bit resolution that detects movement in three directions. The sensor has a maximum range of ± 16 G and detects movements down to 0.04 G. A number of additional functions are available via the two interrupt outputs, such as the sensor can detect activity/inactivity, detect strokes (single pressure, double pressure) and detect whether the sensor is in free fall. Communication to the accelerometer is via I2C or SPI.
