According to the national standard GB7665-87, the sensor is defined as "a device or device capable of sensing the specified measured and converted into a usable signal according to certain rules, usually composed of sensitive components and conversion components." That is, the sensor is a detection device that can sense the information to be measured and can transform the information detected by the detection into an electrical signal or other desired form of information output according to certain rules to meet the requirements of information transmission, processing and storage , Display, record and control requirements. It is to achieve automatic detection and automatic control of the most important part.
As one of the most important means of obtaining information from human beings, sensors play an irreplaceable role in all walks of life. With the development of Internet of Things technology, sensors and wireless sensor technologies become the key to the development of the Internet of Things, which will bring broad prospects for the future development of the sensor industry.
Market, looking forward to blowout
In 2015, the Ministry of Industry and Information Technology Development Research Center for Electronic Components estimated that the world's various sensitive components and sensors market will reach 177 billion US dollars. The next five years, the world's sensor compound growth rate will exceed 10%.
Many related studies show that the Asia-Pacific region will become the most potential sensor market. Intenaud Consulting pointed out that in the global sensor market, the market share in the Asia Pacific region will continue to grow in the next few years and is expected to increase to 38.1% in 2016 with the market share in North America and Western Europe going down slightly. Traffic, information and communication have become the fastest growing areas of the market. It predicts that the global automotive sensor size will reach 41.97 billion euros in 2016, accounting for 22.8% of the global market; the telecommunication industry will reach 42.16 billion euros by 2016, accounting for 22.9% of the global market and is likely to become the largest single application market.
China is gradually becoming the main battlefield in the international competition of sensors. According to statistics, by 2015, the overall market scale of China's Internet of Things will reach 750 billion yuan. Under the driving force of substantial growth of the Internet of Things market, the size of China's sensor market in 2015 reached 121.3 billion yuan. According to CCID Consulting predicts that during the "Thirteenth Five-Year" period, China's sensor market will have a CAGR of over 31%.
Internet of Things to promote sensor compound growth rate over the next 5 years will exceed 10%
This means that, who can successfully seize the Chinese market, is bound to share in the sensor market that piece of cake. As a result, the global multinational giants have stepped up the layout of China's sensing market, local sensor companies have also shown explosive growth. At present, there are more than 1,700 enterprises engaged in sensor production and R & D in our country. However, the overall quality of the industry is uneven and the scale of the enterprises is dominated by small enterprises, accounting for nearly 70% of the total. At the same time, most enterprises focus on the production of low-end products, with price competition as the main reason, and the competition is fiercer. The high-end products are concentrated in leading enterprises and foreign-funded enterprises.
It is foreseeable that in the market-driven, sensor industry consolidation is imperative. Large companies through mergers and acquisitions, control of technical standards and patents, in the "high, refined, sharp" sensor and new sensor market gradually formed a monopoly. Under the competitive pressures of large enterprises, small and medium-sized enterprises (SMEs) have moved toward the concept of "small, fine, small and specialized", developing proprietary technologies and product-specific niche markets.
