The smaller the sensitivity of the sensor, the better the performance of the sensor.

The sensitivity of sensor is an important index to evaluate the performance of sensor. Generally speaking, in the linear range of the sensor, the higher the sensitivity of the sensor, the better the performance of the sensor. At this time, the corresponding output signal to be measured will be larger, which is more conducive to signal processing. However, if it exceeds the linear range of the sensor, with the increase of sensitivity, the external interference unrelated to the measurement will also increase accordingly, thus reducing the performance of the sensor. Therefore, in the linear range, the higher the sensitivity of the sensor, the better the performance, while in the nonlinear range, the higher the sensitivity of the sensor, the lower the performance.

As a detection device, the sensor can convert the sensed information into electrical signals or other necessary forms for transmission to meet the needs of information transmission and processing.
