For the accelerometer and gyroscope, it’s 0圆B. The default I2C address of the magnetometer is 0x1E. Note: The sensor “communicates” with the external modules using an I2C interface. All the readings are provided along three axes. A SparkFun 9DoF stick can measure G-force accelerations from 2 to 16, between 245 to 2,000 degrees per second of angular rotation around the axis, and magnetism between 4 to 16 gauss. In this tutorial, we’ll learn how to interface a SparkFun 9DoF sensor stick with Arduino Uno. What’s referred to as “nine degrees of freedom,” or 9DoF, now combines 3D acceleration with a 3D gyroscope and magnetometer readings - providing accurate readings of an object’s precise position in 3D space. For example, it’s now possible for such a device to not only assess the acceleration forces acting on an object but also of any objects near it (think of autonomous cars, which must take traffic lights, nearby buildings, other vehicles, and pedestrians into account). Since then, the 3D field has advanced considerably.

An accelerometer is an electronic sensor that measures the acceleration forces acting on an object, typically to determine its position in space and monitor the object’s movement. A decade ago, 2D and 3D accelerometers were commonly used in devices to provide the direction, speed, and GPS localization of an object.
