The arrival of the Internet of Everything era has injected "stimulants" into the sensor industry. Sensors are increasingly being applied to various fields of social development and human life, which can be described as "blooming everywhere." 　　While my country's sensor industry is generally at the low-end level, we should face up to the challenges and actively promote industrial transformation and upgrading. Looking forward to the day when China's sensor industry will be among the best in the world.   　　The Internet of Things continues to evolve 　　Inject "stimulants" into the sensor industry 　　U.S./Japan/Germany dominates the sensor market     　　Statistics in 2014 showed that a few economically developed countries accounted for more than 70% of the sensor market. In the future, with the continuous economic growth of developing countries such as China, India, and Brazil, the demand for sensors will also increase significantly, and the market has huge development potential.   Global sensor market size     　　The global sensor market has maintained rapid growth. In 2011, affected by the global economic downturn, the growth rate of the sensor market declined. With the gradual recovery of the global market, the demand for sensors in the market continues to increase.   China's sensor market size     　　The overall quality of my country's sensor industry is uneven, the self-sufficiency rate of high-end products is insufficient, and small enterprises account for nearly 70%. The products are mainly low-end products, and high-end products mainly rely on imports.   Current status and future forecast of global MEMS market output value     　　In recent years, the global demand for MEMS sensor products has increased rapidly. In 2014, the MEMS sensor market exceeded 13 billion U.S. dollars, with an average growth rate of 12% to 13%. The MEMS sensor market is expected to reach 30 billion U.S. dollars in 2020.   Sensor applications "bloom everywhere"     Application of sensors in wearable devices 　　For example, wearable devices are equipped with various sensors to detect and measure heart rate, sweat, temperature, sleep, calories, GPS coordinates, blood pressure, UV ultraviolet rays, and glucose levels. This type of sensor equipment that has formed a market is currently mainly concentrated in three major areas: 　　Motion sensors, including accelerometers, gyroscopes, magnetometers, pressure sensors, etc.; 　　Biosensors, including blood glucose sensors, blood pressure sensors, ECG sensors, etc.; 　　Environmental sensors, including temperature and humidity sensors, gas sensors, PH sensors, etc.   Application of sensors in the automotive industry 　　As we all know, 90% of the innovation in the automotive industry comes from the innovation of automotive electronics. Automotive sensors are front-end systems for information collection and analysis. There are generally two types: one is body perception, including pressure, flow, acceleration sensors and gyroscopes, and the other is environmental perception, including lidar, millimeter wave radar, camera and infrared. Smart sensor equipment such as night vision. The following is a brief introduction to various sensors used in automobiles: 　　Water temperature sensor, used to detect engine coolant temperature (provide engine temperature signal); 　　Throttle position sensor, used to detect the throttle position of the engine (also used to provide engine load signal); 　　Knock sensor, used to detect whether the engine knocks; 　　The intake manifold absolute pressure sensor is used to detect the intake pressure in the intake pipe; 　　Air flow meter, used to detect the quality of intake air; 　　Accelerator pedal position sensor, used to detect the position of the accelerator pedal; 　　Wheel speed sensor, used to detect wheel speed; 　　Vehicle speed sensor, used to detect vehicle speed. 　　In addition, there are wind speed sensors, rain sensors, light intensity sensors, vehicle height sensors, fuel level sensors, fuel temperature sensors, oil pressure sensors, injector lift sensors, and so on.   Application of sensors in the field of industrial automation 　　In an automated production line, sensors are required to monitor each component and feed data back to the control center in order to intervene in time for abnormal nodes to en
