In modern industrial production, especially in automated production processes, various sensors are used to monitor and control the various parameters of the production process, to operate the equipment in a normal or optimal state, and to achieve the best quality of the product. The Chinese sensor market has continued to grow in recent years, with a growth rate of more than 15%. In 2012, China's sensor applications in four areas are industrial control, automotive electronics, communications electronics and consumer electronics.
With the advent of the information age, sensors have become the main way and means for people to access information in the natural and productive fields. In modern industrial production, especially in automated production processes, various sensors are used to monitor and control the various parameters in the production process, to make the equipment work in a normal state or in an optimal state, and to achieve the best quality of the product; In the research, the sensor has a prominent position.
Today, sensors have penetrated into a wide range of fields such as industrial production, space development, ocean exploration, environmental protection, resource surveys, medical diagnostics, bioengineering, and even heritage conservation. It can be seen that the important role of sensor technology in developing the economy and promoting social progress is very obvious. Statistics show that the annual revenue of the global smart sensor market will increase at a rate of 10 per year, reaching $6.9 billion by 2018. The number of sensor devices with processors installed worldwide is currently 65 million units, and by 2019 this number will reach 2.8 trillion units.
