According to the prediction of the Ministry of Industry and Information Technology of China, the Chinese IOT market will exceed RMB 500 billion by 2015, and the CAGR will reach 30% in the next five years. Another name for the Internet of Things is the "sensor network," and the demand for sensors will naturally rise. Overall, the Internet of Things is the driving force for the emerging market and cross-industry sensor market for sensor products, while experience, industrial control, and automotive electronics are the market drivers for the rapid development of sensors.
The manufacture of sensors is currently based on micro-electromechanical (MEMS) and micro-nanotechnology. In particular, MEMS technology has become more and more important as applications expand. Analysis of its application areas, according to the report of research agency Yole recently pointed out that in 2012 the main development driver of MEMS for consumer electronics, especially smart phones as the key product, consumer electronics accounted for about 50% of the entire MEMS market revenue; followed by In automotive electronics and medical electronics, the types of sensors required in these markets focus on inertial sensors such as accelerometers, gyroscopes, and magnetometers, as well as pressure sensors and position sensors.
Among various sensors, the pressure sensor is one of the popular MEMS devices. Yole pointed out that automobiles are the largest market for pressure sensors, accounting for about 74%. A high-end car will be equipped with about 10 pressure sensors. Due to the promising market in the future, many international companies continue to provide more powerful solutions for this area. For example, Freescale's Xtrinsic series is for cars. Electronics has developed a series of sensors. The company has recently introduced three new pressure sensors that will replace the previous MPXHZ6000 series and become new members of Xtrinsic pressure sensors and will be used in automotive engine management and efficiency applications.
According to the forecast report of the United States IC Insights, the global sensor market sales in 2012 will be 8.7 billion US dollars, an increase of only about 2%, such a limited growth rate is mainly due to the poor global economy, especially in Europe and the United States demand Caused. At the same time, however, under the influence of the development of the Internet of Things industry, the level of demand for sensors in the Chinese mainland market is gradually increasing.
