Abstract
A smart temperature sensing device 10 includes a sensor 16 and a memory 25 on a sensor unit 14. The memory contains a plurality of custom nonlinear calibration coefficients which uniquely characterize the sensor 16. A temperature system includes the smart temperature sensing device 10 and a FSAU 12 having a processor 28 which downloads the calibration coefficients and utilizes them in converting electrical signals from the sensor 16 into temperature values that represent the temperature at the sensor 16. A method of calibrating a sensor 16 includes measuring an output signal of the sensor 16 over a temperature range, thereby obtaining a plurality of paired data points. The paired data points are used in a curve-fitting algorithm to obtain coefficients to a polynomial that characterizes the nonlinear temperature-voltage relationship of the sensor 16. The coefficients are stored within the memory 25 until downloaded by the processor 28 for use in signal conversion.
