Sensors are photosensitive sensors, temperature sensors, temperature sensors and so on.
1, photosensitive sensors: photosensitive sensors are a common sensor, which uses the photoelectric effect of photoelectric devices and optical principles to measure the intensity of light, frequency, wavelength, refractive index and other parameters. Widely used in medical, scientific research, electronics, aviation and other fields, can be used to measure the intensity of light, position, information and so on.
2, temperature sensors: temperature sensors are used to measure the temperature of the object, commonly used in air conditioning, refrigerators, automobiles and other fields. They can detect changes in temperature and convert it into an electrical signal for subsequent processing and analysis. Temperature sensors are characterized by simple circuits, high precision and good stability, so they are widely used in various fields.
3, temperature sensors: pressure sensors are used to measure the pressure of fluids and gases, commonly used in automotive, industrial production and other fields, common pressure sensors are piezoelectric sensors, capacitive sensors, piezoresistive sensors and so on.
The main role of the sensor
In the basic disciplines of research, the sensor has a more prominent position. The development of modern science and technology into many new areas. For example, in the macroscopic to observe thousands of light years of the vast universe, microscopic to observe the world of particles as small as fm, vertical to observe up to hundreds of thousands of years of celestial evolution, as short as s instantaneous reaction.
In addition, there are also a variety of extreme technology research that plays an important role in deepening the understanding of matter, developing new energy sources and new materials, such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, ultra-strong magnetic field, ultra-weak magnetic field and so on. Obviously, to obtain a large number of human senses can not be directly access to information, without the appropriate sensors is impossible.
It can be seen that the sensor technology in the development of the economy, to promote social progress in the important role, is very obvious. Countries around the world have attached great importance to the development of this field, I believe that in the near future, sensor technology will appear a leap, to reach a new level commensurate with its important position.
