Before talking about accuracy and linearity, let us talk about the concepts of several errors:

1. Absolute error: the difference between the measured value and the ideal value;

5. Linear error: the deviation between the measured curve and the ideal straight line;

Accuracy: The change limit is determined by the sensor's basic error limit and the influence amount (such as temperature change, humidity change, power supply fluctuation, frequency change, etc.).

Linear range: the measurable range of the sensor in linear operation.
