The characteristics of sensors themselves: The internal structure and material selection of sensors directly affect their accuracy. For example, the quality, stability, and nonlinear errors of sensor sensitive components can have an impact on accuracy.

　　Temperature change: Temperature changes can cause changes in the physical properties of the internal components of the sensor, thereby affecting accuracy. To improve accuracy, it is usually necessary to perform temperature compensation or use temperature stable materials.

　　Environmental conditions: Factors such as vibration, humidity, and electromagnetic interference in the environment can also affect the accuracy of sensors. Therefore, when using sensors in special environments, it is necessary to consider these factors and take corresponding measures.

　　Installation and calibration: The installation position and method of the sensor, as well as the calibration method, can have an impact on accuracy. Proper installation and calibration can maximize the accuracy of sensors.
