Description

This is a high resolution digital accelerometer providing you at max 3.9mg/LSB resolution and large ±16g measurement range. It's base on an advanced 3-axis IC ADXL345. Have no worry to implement it into your free-fall detection project, cause it's robust enough to survive up to 10,000g shock. Meanwhile, it's agile enough to detect single and double taps. It's ideal for motion detection, Gesture detection as well as robotics.

Usage

Every accelerometer has been individually tested before shipping to you. But in rare cases, you might need to reset the zero-offset by yourself.

Here below we show you how to read the raw data and obtain data in the unit of g, AKA g-force, from this accelerometer.

1. Plug it onto the I2C port of your Crowtail- Base Shield.

2. Download the Crowtail- 3-Axis Digital Accelerometer Program and unpack it into arduino-1.0\libraries in your Arduino installation folder.

3. Open the demo code directly by the path:File -> Example ->DigitalAccelerometer_ADXL345->ADXL345_demo_code.

4. Upload the code and open the serial monitor.

5. Open the serial monitor to check the result.

The outputs of this sensor consist of two parts: raw data and 3-axis acceleration info converted into the unit of gravity, "g".
