Sensing technology is the study of sensor material, design, process, performance and application of a comprehensive technology. Sensing technology is a edge technology, it involves physics, mathematics, chemistry, materials research and development of its sensitive element chip research and application.

Sensor information acquisition system is a kind of to the physical quantities, such as chemical content, biomass non-electricity conversion to electricity devices. Output signals have different forms, such as voltage, current, frequency, pulse, etc., can satisfy the information transmission, processing, record, display, control requirements, is widely used in the field of multiple disciplines. Many developed countries of the world are speeding up research and development of new technology of sensor, and have made significant breakthrough. In scientific research and basic research, the sensor can get human senses are unable to get a lot of information. Such as sensors and sensor technology, a tiny particles can be observed; To measure a very short time. A spaceship can be thought of as a collection of high performance sensor, can capture and collect all kinds of information from the universe; We used in a car there are as many as hundred kinds of sensors, the sensor can be used to measure the oil temperature, water temperature, pressure, flow, displacement, speed, attitude, etc.

The level of the sensor is to measure a country one of the symbols of comprehensive economic strength and technological level. Its level of development, production capacity and application field has become an important symbol of a nation's scientific and technological progress, as some experts consider that abroad; Who dominated the sensor, who dominated the new era. Sensor technology (non-electricity measurement technology) is an important branch of modern science and technology, it is information science position of "outposts", namely the necessary means of information capture. In today's information age, with the development of the automatic detection, automation technology, sensor technology is more and more important, it holds the lifeline system, pushing forward pace of science and technology, there is no sensor has been the rapid development of modern science and technology.
