Temperature Sensor Calibration
RF Code R150, R151 and R155/R156 sensor tags have temperature-sensing components that are calibrated at the factory
during the manufacturing process. These are silicon-based chips that don’t require field calibration or re-calibration over
time. As the ambient temperature moves toward the extremes, sensor accuracy decreases slightly. The chart below
illustrates this concept.
