What is the sensitivity of the sensor?

This sentence refers to the response degree of the sensor to the change of the input signal, that is, the ratio of the output change of the sensor to the input change that causes the output change.

The sensitivity of sensor is usually expressed by the change of sensor output caused by the change of unit input signal.

The higher the sensitivity, the more sensitive the sensor is to the change of input signal, and the smaller the change can be detected. Sensitivity is one of the important indexes to evaluate the sensor performance. For many applications, sensors with high sensitivity can provide more accurate measurement results.
