The function of the sensor is simil

The function of the sensor is similar to the human sense organ. It converts the measured, such as force, displacement, temperature, etc., into an easy-to-measure signal and sends it to the signal conditioning link of the measurement system. The sensor can also be regarded as an extension of human senses, because the sensor can be used to explore things that people cannot directly measure with the senses, such as macroscopic observation of the vast universe of thousands of light years, microscopic observation of the particle world as small as fm In order to observe the evolution of celestial bodies for hundreds of thousands of years, the instantaneous response as short as S.
