Sensor calibration is set of tasks performed under certain conditions to
establish the relationship between the physical quantity measured (as an output
of a sensor) and the corresponding measurement uncertainty. Often, calibration
is being conducted by comparing the measurement to a measurement of more
accurate sensor (e.g. sensors with resolution
and accuracy of one order higher). Calibration verifies the precision,
reproducibility and reliability of measurement results. The result of
calibration is typically a calibration function, curve, table or a diagram.
