1. A method for processing glucose sensor data, the method comprising:

  • applying a potential to a glucose sensor at a first setting;

    measuring a first signal from the glucose sensor at the first setting;

    switching the potential to a different setting;

    measuring a second signal from the glucose sensor at the different setting;

    modifying a glucose concentration associated with the first signal by accounting for an adjustment derived from the second signal;

    generating glucose concentration data, using a processor coupled to a memory of a sensor electronics unit, based at least in part on sensor data received from the glucose sensor;

    displaying, using a display, a first screen presenting generated glucose concentration data over a first time period;

    displaying, using the display, a second screen presenting generated glucose concentration data over a second time period, wherein the second time period is different in length from the first time period;

    displaying, using the display, a third screen presenting a single generated real-time glucose concentration value;

    receiving an input from a user to toggle between the first screen, the second screen, and the third screen of the display;

    receiving an input from the user related to mealtime information, wherein the mealtime information is displayed on the display;

    receiving information from the user related to a glucose concentration target range, wherein the glucose concentration target range is represented by an upper boundary and a lower boundary, and wherein the upper boundary and the lower boundary are user configured; and

    generating an alert responsive to detection of a hyperglycemic condition or a hypoglycemic condition based at least in part on the single generated real-time glucose concentration value being outside the glucose concentration target range.
