1. A sensor for measuring data, comprising:

  • a housing;

    a circuit board assembly disposed with the housing, the circuit board assembly including a wireless transmission element and at least one of an accelerometer and a gyroscope; and

    a power source electrically coupled to the circuit board assembly to provide power to components of the circuit board assembly;

    wherein the sensor is configured to be attached to an object and measure data associated with the object regardless of an orientation of a coordinate system of the sensor with respect to an orientation of a coordinate system of the object,wherein the coordinate system of the sensor comprises;

    an x-axis that includes a center of the sensor on an outer surface of the housing and a defined location on the outer surface of the housing a distance away from the center;

    a z-axis that includes the center of the sensor and extends vertically upwards such that it is approximately perpendicular to the outer surface of the housing; and

    a y-axis that is a cross product of the x-axis and the z-axis, andwherein an angle defined by the y-axis of the coordinate system of the sensor and a y-axis of the coordinate system of the object is determined and accounted for when measuring data associated with the object, the angle being able to have a non-zero value,wherein the angle defined by the y-axis of the coordinate system of the sensor and the y-axis of the coordinate system of the object is determined based on one or more rotational velocity vectors measured by the gyroscope along the x-axis and the y-axis of the coordinate system of the sensor, andwherein a determination of the angle defined by the y-axis of the coordinate system of the sensor and the y-axis of the coordinate system of the object is determined in part based on a detection and measurement by the gyroscope of a rotation about a z-axis of the coordinate system of the object, wherein the detection and measurement by the gyroscope is a detection and measurement by one and only one gyroscope of one and only one sensor.
