1. A system for measuring an analyte concentration in a host, the system comprising:

  • a sensor system comprising;

    a first component comprising a transcutaneous analyte sensor, wherein the transcutaneous analyte sensor is configured to measure a signal indicative of an analyte concentration in the host, wherein the transcutaneous analyte sensor comprises;

    an in vivo portion configured for insertion and existence within a living body of the host during sensor use; and

    an ex vivo portion configured to remain outside the living body of the host during sensor use; and

    a second component comprising sensor electronics configured to operably connect with the transcutaneous analyte sensor during sensor use, wherein the sensor electronics comprise;

    one or more memories configured to store;

    data representative of analyte concentrations derived from signal measurements from the transcutaneous analyte sensor; and

    sensor calibration information for calibration of the transcutaneous analyte sensor without requiring a reference analyte value;

    wherein the first component is unconnected to the second component in a first state, wherein during a second state the first component is configured to be connected to the second component by the host to form an assembly prior to the assembly being affixed to the host for sensor insertion.
