In recent years, flow sensor, pressure sensor, temperature sensor in our market is the largest, accounting for the entire sensor market 21,19 and 14; Pressure sensors, temperature sensors, flow sensors, level sensors have shown the characteristics of a mature market. It is expected that the main growth of the future sensor market will come from wireless sensors, micro-system sensors, biosensors and other emerging sensors. Sensors have entered people's daily work and family life, and have been widely used in various sectors of the national economy and national defense construction, China's modernization has made due contribution.

　　In recent years, the rapid development of the Internet of things in the Chinese market, further pulling up the demand for sensor products. According to the forecast, the next five years domestic sensor market compound annual growth of 31.5% . The sensor market in the fields of automobile, logistics, coal mine safety supervision, security and RFID tag card is growing rapidly.

　　At the same time, Chinese sensors are influenced by a combination of scientific and technological forces, and local sensor wealth is still in a very strong position. At present, there are 1688 enterprises and historic sites in our country, which are engaged in the development, production and monopolization of sensors. The lack of full typology leads to the problem of low skill but high price of sensors in our country, which loses its advantage in the domestic market and makes the market more fierce.

　　At present, sensors are more and more applied to social development and various fields of human life, such as industrial automation, agricultural modernization, aerospace technology, military engineering, robotics, resource development, ocean exploration, Environmental monitoring, security, medical diagnosis, transportation, household appliances, etc. . In recent years, the global sensor industry has developed rapidly. In 2008, more than 3,000 global sensor manufacturers had total sales of $50 billion, while the world sensor market in 2010 reached more than $80 billion. With the rapid development of Internet of things, the domestic sensor industry also ushered in a golden period of development.

　　By 2015, the overall market scale of our country's Internet of things will reach 750 billion yuan, and the sensor industry will benefit directly from it. In 2010, our sensor manufacturing enterprises (annual sales revenue of more than 500 million yuan) achieve sales revenue of 44.027 billion yuan. According to industry experts, China's sensor market will develop steadily and rapidly from now on. Driven by the rapid growth of the Internet of things market, the scale of China's sensor market is expected to reach more than 120 billion yuan in 2015.
