1. A sensor comprising:

  • a sensor body;

    an emitter and a detector disposed adjacent the sensor body;

    a temperature-based tissue contact sensor disposed adjacent the sensor body, wherein the temperature-based tissue contact sensor is configured to provide an electrical feedback signal related to distance between the temperature-based tissue contact sensor and tissue of a patient; and

    an encoder comprising stored data or code related to the temperature-based tissue contact sensor, wherein the stored data or code is configured to be read by a monitor to cause the monitor to select a set of instructions for processing the electrical feedback signal from the temperature-based tissue contact sensor and determining if the temperature-based tissue contact sensor is in contact with the tissue of the patient.
