Abstract: In one embodiment a method for sensor reader calibration comprising: performing a calibration of a sensor reader wherein the calibration comprises open circuit calibration, a short circuit calibration, and a load circuit calibration, or any combination thereof in any succession; enabling connection of a pickup coil to the sensor reader to measure a sensor response; and applying a baseline correction to the sensor response, wherein the baseline correction is obtained utilizing measurements from the calibration step. In a further embodiment, a method for sensor response calibration incorporating environmental correction comprising: measuring a first resonance impedance spectrum of the sensor with a first applied power to the pickup coil; measuring a second resonance impedance spectrum of the sensor with a second applied power to the pickup coil; and applying a correction to the sensor response corresponding to the respective measured first and second resonance impedance spectrum to mitigate for environmental parameters.
