Triple Axis Accelerometer Module (ADXL 345)

Description

The ADXL345 is 3-axis accelerometer with high resolution measurement at up to +/-16 g. Digital output data is accessible through either a SPI (3 or 4 wire) or I2C digital interface. The ADXL345 is well suited to measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0 The excellent sensitivity (3.9mg/LSB 2g) provides high-precision output up to +/-16g. Features 2.0-3.6VDC Supply Voltage Ultra Low Power: 40uA in measurement mode, 0.1uA in standby 2.5V Tap/Double Tap Detection Free-Fall Detection SPI and I2C interfaces Dimensions: 21mm x 16mm ADXL345 datasheet (from Analog Devices) Arduino example and how to connect ADXL345 quick start guide (from Analog Devices)
