Sensors and Calibration

A sensor converts a physical quantity into a signal. Calibration maps signal to a reference value and identifies range, sensitivity, offset and uncertainty.

Core checkpoint: Never extrapolate beyond a calibrated range without evidence.

Which statement best captures the core checkpoint for Sensors and Calibration?

Never extrapolate beyond a calibrated range without evidence.

Choose a solution before defining the evidence.

Ignore units, limits and boundary cases.

Assume the first result applies in every context.

Enter the highlighted key term for Sensors and Calibration. Checkpoint clue: What does sensor sensitivity describe?

Which lesson most directly explains the concepts used in this application?

A soil-moisture sensor must be calibrated for the local soil rather than copied blindly from a web table.
