Sensor technology is one of the high new technologies that have developed in today's world. It is also an important sign in the development of contemporary science and technology. It is one of the three pillars of the information industry with communication technology and computer technology. It is because the world's countries have generally attached importance to and investment, and the sensor has developed very rapidly. There are currently more than 6,500 production units in the world. The United States, Europe, Russia has been engaged in sensor research and manufacturers more than 1,000 manufacturers, and more than 800 Japan.
In recent years, the global sensor market has been rapidly increased, and the growth rate of 2009 and 2010 has reached more than 20%; in 2011, the growth rate of sensor market fell 5% in 2010, and the market size is $ 82.8 billion. With the gradual recovery of the global market, the 2012 global sensor market has reached $ 95.2 billion, with approximately $ 105.5 billion in 2013. As the economic environment continues to improve, the market's demand for sensors will increase, and the market size has exceeded $ 170 billion in 2016, and the growth rate reached 9.7%.
Chart 1: 2010-2017 Global Sensor Market Situation (Unit: 100 million US dollars,%)
At present, the global sensor market is primarily dominated by several leading companies in the United States, Japan, Germany, of which the United States, Japan, Germany occupies nearly 70% market share.
Chart 2: Global Sensors Area Distribution
Domestic enterprises are weak, and the sensor market is 70% of foreign enterprises.
The main manufacturer of the global sensor market has GE sensors, Emerson, Siemens, Bosch, STMicroe, Honeywell, ABB, Japan Henghe, Omron, Schneider Electric, E + H, etc., 70% in China's sensor market The share is occupied by these foreign companies.
At the global consumer inertial sensor (accelerometer + gyroscope) market, the semiconductor is in the market leader, accounting for about 40% of the market share, and Xuhua has become a microelectronics, and the Bosch is followed, these four The inertial sensor manufacturer accounts for 75% market share.
Magnetometer (3-axis electronic compass) and 6-axis electronic compass (magnetometer + accelerometer) because there is a consumer product represented by smartphones because there is a strong positioning function. Among them, Japanese Asahi is a long-term raw position of the microelectronics, and the market share of electronic compass in the smartphone field is as high as 80%.

Sensor as the heart of the Internet of Things, huge development space
The system architecture of the Internet of Things is generally composed of a sensing layer, a transport layer, and an application layer, wherein the perceived layer is mainly composed of a sensor, a microprocessor, and a wireless communication transceiver. According to McKinsea report, the economic benefits brought by the 2025 Internet of Things will be between 2.7 trillion to $ 6.2 trillion. Among them, the sensor as the entrance to the data collection, the "heart" of the Internet of Things, will usher in huge development space.
