  • Sensor basic tutorial knowledge(3)

    Static characteristics of the sensor The static characteristics of the sensor are related to the static input signal, the output of the sensor and the input. Since the input and output are independent of time at this time, the relationship between them, that is, the static characteristics of the ...

  • Sensor basic tutorial knowledge(2)

    Sensor classification At present, there is no unified classification method for sensors, but the following three types are commonly used: 1. According to the physical quantity of the sensor, it can be divided into sensors such as displacement, force, speed, temperature, flow, and gas composition....

  • Technical approach to improving sensor performance

    1. Sensor noise and its reduction measures Sensor noise refers to all unwanted signals that appear in the sensor in addition to the signal being measured. It can be generated internally by the sensor or mixed with the signal from the outside. In general, noise is an irregular change, periodic flu...
