1. A method for calibrating a second continuous analyte sensor using sensor data from a first continuous analyte sensor, comprising:

  • receiving sensor data from a first continuous analyte sensor, wherein the sensor data is indicative of a glucose concentration in a host;

    determining a conversion function, using a processor module, wherein the conversion function comprises a slope and a baseline, wherein the slope is representative of a sensor sensitivity;

    converting the sensor data using the conversion function;

    receiving sensor data from a second continuous analyte sensor; and

    calibrating the sensor data from the second continuous analyte sensor using the sensor data from the first continuous analyte sensor, including providing calibration information, including data about the sensor sensitivity, to the second continuous analyte sensor to increase its intelligence and enhance its performance, wherein the calibrating includes constructing a first curve from the sensor data from the first continuous analyte sensor and constructing a second curve from the sensor data from the second continuous analyte sensor and matching the first curve with the second curve.
