People in order to get information from the outside world, must resort to the sense organs. The people rely on their own senses sensor classification, in the study of natural phenomena and laws as well as production activities in their function is far from enough. To accommodate this situation, we need sensors. Therefore we can say, the sensor is an extension of human facial features, also known as electric facial features. The arrival of the new technological revolution, the world began to enter the information age. In the use of information in the process, we must first solve is to obtain accurate and reliable information, and the sensor is to obtain the main ways and means of production in the field of natural and information. On the basis of interdisciplinary research, the sensor is more prominent position. The development of modern science and technology, sensor prices into many new areas: for example, at the macro to observe thousands of light-years of the vast universe, to observe the microscopic particles as small fm world longitudinally to observe tens of millions of years cosmogonic sensor type, short to s instant reaction. In addition, there have been various studies extremist material on deepening awareness of technology, develop new energy, new materials, have an important role, as ultra high temperature, cryogenic, ultra, ultra high vacuum, magnetic super, super weak magnetic fields, etc. Obviously, to obtain a lot of information can not directly obtain the human senses, there is no sensor adapted to be impossible. Many basic scientific obstacles sensor, the first object is to obtain information on difficulties exist, and some of the new mechanism and the emergence of high-sensitivity detection sensor, often lead to breakthroughs in the field. Develop some sensors, often some interdisciplinary pioneer in the development. Classification sensor, sensors, Xinfeng Xinfeng sensing provided by Xinxiang purification technology Limited.
