The environmental monitoring sensor market is progressing rapidly, creating an international sensor industry park, China's "sensing valley"

The sensor market has progressed rapidly, and the civilian market has stepped up. Domestically produced instruments can basically replace imported products. With the in-depth implementation of energy conservation and emission reduction work in my country and the increasing attention of the people to environmental issues, environmental monitoring sensors are playing an increasingly important role in our daily production and life. It is estimated that by 2020, the scale of the mainstream gas sensing industry will reach more than 60 billion yuan. In the future, it is expected to achieve annual sales of more than 200 billion yuan and maintain an annual growth rate of more than 20%.

At present, whether it is industrial, commercial, public environment, civil, or other gas sensors with different working principles, it can basically be made in China. According to the application field, environmental monitoring sensors are mainly divided into three categories. The first category is sensors for analytical instruments, which are mainly used in instruments used by environmental monitoring stations, environmental testing or measurement calibration institutions, and scientific research institutes. They are characterized by high accuracy, large size, and high price. Foreign brands in this field occupy the mainstream market.
The second category is industrial environmental monitoring sensors, including indoor and outdoor environmental monitoring on the job site, indoor monitoring of flammable, explosive or toxic and harmful gases such as organic vapor, combustible gas, etc. according to the job site environment; outdoor monitoring mainly monitors the emission of VOC concentration, specifically ammonia Various pollutants such as gas, benzene, toluene, etc. At present, domestic and imported products in this field are equally divided.
The third category is civil environment monitoring sensors, which are mainly used for indoor and outdoor residential homes or ordinary commercial places such as shopping malls, stations, airports, schools, and roads. With the emphasis on respiratory health in recent years, this field has developed rapidly.
At present, the main demand in the civilian field is to realize the function of measuring particle size (PM2.5) and to monitor natural gas and coal gas, while the monitoring of formaldehyde and TVOC has not yet been widely used. Although the imported semiconductor sensors widely used in the civilian field are low in cost, they have high airiness and poor accuracy; electrochemical/catalytic combustion sensors are also prone to reduced accuracy after a long period of use; laser, infrared and other spectra Although the sensor has high accuracy, it is large in size and expensive. At present, it is mainly used in high-end markets such as industry and environmental protection.
Constrained by the basic problems of industrialization such as new materials, equipment, and production processes, the backward sensor R&D and manufacturing level in China is in contradiction with the rapid growth of demand and can only rely heavily on imports. Because many domestic manufacturers do not master core technologies and my country does not have a unified industry standard, domestic application companies have low trust in manufacturers. In order to maintain the consistency and stability of the system, they dare not use domestic products. This also makes some domestic manufacturers Increasingly lack of self-confidence. Not only in the field of environmental monitoring sensors, this is a common problem in my country's overall sensor industry.
Generally speaking, there is no gap between the basic functions and daily use of domestically developed industrial environment sensors and detection products and foreign products, and most of them can be interchanged. However, there is still a certain gap with foreign products in some technical details, processing technology, extreme environment use, etc. This is the direction for our improvement. This is also a common problem faced by domestic sensor brands, and even a transformation problem faced by the entire Chinese manufacturing industry. We need to change from the pursuit of "quantity" to the pursuit of "quality" in the past.
To promote the application of domestic sensor products, we should start from the following aspects: First, domestic sensor companies should start from their own, increase investment in technological innovation, continue to optimize technology and process details, and achieve the "last centimeter" of comparison between these fields and imported products. Make breakthroughs and continue to leverage the inherent advantages in domestic market applications, channels, services, prices, and industrial ecosystems to achieve overall strength enhancement and promote market-oriented applications. Second, the state should actively create a fair and transparent business environment, eliminate the discriminatory nature of the sensor application side, and encourage the application side to comply with market value and behavior rules when purchasing sensors. For example, it should be prohibited to specify that imported products must be used in bidding. Third, to open up the channel for the industrialization of scientific research results, the scientific research results produced by the national public scientific research platform should be provided to the society in the form of public products. Give full play to the role of industry alliances, actively, objectively, meticulously, and continuously accumulate domestic and foreign sensor industry technology and industry materials, promote standardization and industry collaboration, and help the development of the sensor industry. Finally, as a basic subject in the upstream of the industry, sensors can be used in many areas for secondary development and application, and there is basically no problem of industrial ecological cycle. Combined with the current hot smart manufacturing, robotics, smart wear, smart health, smart home and other specific fields, the state should advocate, organize, and provide more resources to participate, and together push China's sensor and Internet of Things industry to a higher level.
Integrate existing resources at home and abroad, and create a "dual ecological" industrial chain with a good natural environment and superior industrial environment in suitable areas in China-the international sensor industry park, China's "sensing valley". Through industrial agglomeration, within 5 years, a global only international company with a reasonable structure, a complete industrial chain, outstanding industrial advantages and brand characteristics, and an international market connection capability and popularity will be formed with more than 500 companies and scientific research institutes. The chemical sensor industrial park is expected to achieve annual sales of more than 200 billion yuan and maintain an annual growth rate of more than 20%.
