1. An analyte sensor unit comprising:

  • a housing adapted for placement on the surface of skin having a bottom surface for contacting with the skin and wherein the housing comprises;

    an electrochemical sensor comprising a plurality of electrodes including a working electrode, wherein the sensor comprises a portion within the housing and a portion exterior to the housing to permit insertion of the electrochemical sensor to a depth of about 2 to about 7 mm beneath the surface of the skin, wherein the electrochemical sensor comprises a substrate comprising all of the plurality of electrodes;

    sensor electronics comprising an RF communication unit for communicating data obtained by the electrochemical sensor, the sensor electronics coupled to the electrochemical sensor through the electrical contacts, wherein the sensor electronics comprise electrical contacts that are positioned between at least a portion of the electrochemical sensor and the bottom surface of the housing; and

    a readable or readable/writable memory for storing factory determined calibration information for calibrating the electrochemical sensor, wherein the electrochemical sensor does not require user-implemented calibration following insertion of a portion of the sensor beneath the surface of the skin; and

    an adhesive disposed on the bottom surface of the housing to attach the housing to the surface of the skin.
