Readings are dependent on what?

Readings are dependent on what?

• A. Battery Level
• B. Humidity
• C. Calibration
• D. Temperature

Answer: (C)

Calibration ensures readings reflect real-world values by translating raw sensor signals into accurate measurements. Sensors output signals that must be mapped to units through a calibration curve or coefficients obtained from reference standards. As sensors age or conditions change, that relationship can drift, so keeping calibration up to date is what keeps readings trustworthy. If calibration isn’t current, even a well-behaved sensor can produce biased or inconsistent results. Factors like battery level, temperature, or humidity can influence readings by affecting sensor behavior or electronics, but they don’t by themselves provide the essential link between the signal and the real quantity—that link comes from calibration.
