The Internet of Things acts to collect or acquire various physical quantities, chemical quantities, and biomass in nature. Sensors turn various physical quantities, chemical quantities, and biomass of nature into measurable electrical signals. As a whole system of the concept of the Internet of Things, in the three levels of perception, transmission and application, sensors must complement each other for the Internet of Things, sharing the burden of honor and disgrace.
With the development of the Internet of Things and the wide application of intelligent terminals, the demand for sensor products has increased significantly, and the focus has gradually turned to the field of MEMS sensors with high technology content.
Yole Developement data shows that the global demand for MEMS sensor products has increased rapidly in recent years. In 2017, the market size of MEMS sensors was 43.76 billion yuan, with an average growth rate of more than 15%. It is expected to reach 72.1 billion yuan in 2020.
The global sensor market has maintained steady and rapid growth for many years. The smart sensor industry's three-year action guide proposes that by 2019, China's smart sensor industry has made significant breakthroughs, and the industrial ecology is relatively perfect. A number of innovative capabilities and strong competitive advantages have emerged. The international advanced enterprise, the technical water is steadily improved, the product structure is continuously optimized, and the supply capacity is effectively improved. The scale of the industry is growing rapidly. The scale of the smart sensor industry reached 26 billion yuan; 5 enterprises with main business income exceeding 1 billion yuan and 20 enterprises with over 100 million yuan.
Sensors are an important role in the industry 4.0 era. With the application of the Internet of Things in the industrial field, more and more devices need to use sensors to collect data, further explore the value of data, improve equipment efficiency through data analysis, and predict some possible occurrences. Things, reduce downtime losses, and make the factory closer to market demand.
Smart cities are connected to objects in the city, and sensors need to be installed on every object that needs to be identified. Therefore, the upgrading of sensors has become the key to the rapid development of smart cities. The small Spanish town of Santander is the city of sensors. Buildings and streetlights are filled with 25,000 sensors for measuring light, noise, carbon emissions, temperature, humidity and pressure; roadsides have geomagnetic sensors that monitor roads and parking conditions.
Agricultural sensors have brought traditional agricultural production to the path of intelligent agriculture, which is intelligent, automated and remotely controlled. Through sensors, we can get rid of the natural factors such as weather and realize remote scientific monitoring in fields such as fields, greenhouses, aquatic products and livestock, effectively reducing human consumption. It is also possible to use scientific analysis to improve the ability of the entire agricultural industry to resist risks and increase agricultural productivity.
The core of the development of the Internet of Things lies in the deployment of sensors. Over the years, due to the widespread application of the Internet of Things, the sensor industry has ushered in tremendous development opportunities. In 2019, the global sensor market is expected to exceed US$ 266 billion, especially in China.
With the rapid growth of sensor deployment, the Internet of Things is booming, providing a solid foundation for the development of cloud platforms. The cloud provides storage, management, and analysis as data generated by various devices after networking. The core of the cloud platform lies in the data distribution center. The use of data collected by the Internet of Everything will create many innovative business models and applications.
At the same time, the sensor is deployed on a larger scale, and the potential value of the collected big data will be gradually tapped. Data generation, collection, processing, decision-making and application can be said that the Internet of Things is driven by “data”. industry. That is to say, the vast amount of data generated by the Internet of Everything is intelligently processed and analyzed, and finally forms products or services through data. It is the core business value of the Internet of Things that will create more innovative business opportunities for the society.
The development of the Internet of Things has become the key direction of technology and industrial innovation at the national level. The technical environment for promoting the industrialization and large-scale development of the Internet of Things has been basically in place. In order to ensure the scale-oriented development of the Internet of Things, especially in the technical standards and independent intellectual property rights. Relevant policies such as information security have become one of the main driving forces for accelerating the development of the Internet of Things. In recent years, China's Internet of Things industry has grown at a rate of more than 20%. In 2017, the size of China's Internet of Things market exceeded 100 billion yuan.
With the development of the Internet of Things faster and more widely used, as the most important sensor of the Internet of Things perception layer, the future will be a good time for development and there is a very large space for development. The development prospects are very objective. It is foreseeable that special sensors for special industries and sensors with high precision will have a lot of room for development.
