Sensor industry is at a critical stage of development from the traditional to the new sensor, it reflects the general trend of the development of new sensor miniaturization, multi-functional, digital, intelligent, systematic and network. China sensor production process of industrialization, should take into account two aspects of the introduction of foreign technology and independent innovation. The introduction of foreign advanced technology, can improve their skills, but also to meet the needs of the domestic market, the sensor production scale of the industry.
As a physical device or a biological organ, the sensor is not only able to detect, and feel the external signal, the physical conditions (such as light, heat, humidity) or chemical composition (such as smoke), can also be used to ascertain the information is passed to the other devices or organs. At present, the sensor has penetrated such as industrial production, space exploration, ocean exploration, environmental protection, resource survey, medical diagnostics, bio-engineering, and even cultural relics protection, and so on extremely wide range of areas. From deep space to the vastness of the ocean, as well as a variety of complex engineering systems, almost every modern project, are inseparable from a variety of sensors. Because it is the extension of the human senses, electric facial features, it is also known to have unshakable position.
"No sensor would be no modern science and technology" point of view has been recognized around the world. The detection system sensor as the core, continue to provide all the information of the macro and micro world to humans, like nerve and sensory awareness and transform the nature of a powerful tool. The visible sensor technology plays an important role in economic development, and to promote social progress.
