    Three years of the epidemic, difficult to travel, difficult to go abroad, the most basic needs of human survival, face-to-face communication is seriously limited. The sensor application exhibition Sensor Shenzhen in Shenzhen, carefully planned by China Sensor Internet of things Industry Alliance, seems to ignite a "fuse" in the field of sensor technology and detonate the sensor circle in China and even in the world.

      Three years of the epidemic, the sensor circle of friends, the sensor community seems to be too far apart; three days of Shenzhen sensor exhibition, old friends heartily unleashed the strength for three consecutive years, friends from the United States and brothers in Hong Kong shook hands tightly; the elite from Germany and experts from the Northeast cheered frequently; tycoons from the Middle East looked for opportunities for Chinese sensors.
    Technology from Japan is looking for the sensor market in China; customers from commercial electronics and suppliers from the industrial sector also learn from each other; manufacturers from aviation are also trying to find civilian customers.
     The sensor technology is broad enough, the application of the sensor is wide enough, and the market of the sensor is big enough, so that we can embrace the spring of the sensor as much as we can.

     Looking through the sensor exhibition for three days, in order to observe China's sensor market, Google has the following impressions:
     First, the sensor industry is really "hot". If there is no impact of the epidemic, it may be even hotter. Need local governments according to their own characteristics and current situation, enhance their strengths and avoid weaknesses, differential development, try to avoid a swarm of bees, myopia. According to the meetings I attended and the information I have.
    Harbin, Shenyang, Beijing, Taiyuan, Qingdao, Zibo, Jinan, Yantai, Zhengzhou, Xinxiang, Shanghai, Nanjing, Wuxi, Suzhou, Changzhou, Xuzhou, Xi'an, Baoji, Hanzhong, Hangzhou, Jiaxing, Ningbo, Wenzhou, Wuhan, Changsha, Zhuzhou, Chengdu, Deyang, Chongqing, Fuzhou, Quanzhou, Xiamen. More than 30 large, small and medium-sized cities, such as Shenzhen, have made it clear to develop and support the sensor industry.

    Second, most people in the government do not really understand the characteristics and current situation of the sensor industry, and do not realize the complexity of sensor technology, the intensity of sensor investment, and the fragmentation and multifaceted nature of the sensor market.
     Still focus on GDP, not on the fundamentals of technology. Some people unilaterally think that the sensor industry is the semiconductor industry or integrated circuits; some people unilaterally think that MEMS technology is the whole of sensors; some people unilaterally think that instruments are sensors.

      Third, the investment community pays attention to "hot spots" and lacks patience, underestimating the time it takes to develop and engineer each sensor.
     They are used to "fast" food, used to "express" business, accustomed to "high-speed rail" speed, but forget the sensor technology, especially the process requires long-term accumulation. Huawei's temporary "pause" is a case in point. Only with its own core technology will Huawei not be "stuck" by foreign threats.

      Fourth, the sensor industry lacks enough patience to develop technologies or products with their own characteristics, with serious homogenization and serious competition, because we have to live first.
      It can be seen from the exhibition that there are dozens of companies for industrial pressure sensors, oil-filled cores or transmitters made of them, and more than a dozen for gas sensors, optical semiconductor principles and general optical principles, but there are very few companies that really start with wafers or foundations.

    Fifth, compared with their counterparts in foreign developed countries, the scale of Chinese sensor enterprises is generally on the small side.
    It not only needs the attention of the investment community, but also needs the enterprise to have an international vision, not only on the domestic, but also on the global market.
    The sensors needed by consumer electronics and those needed by industry have obviously different mass and technical requirements, and should be developed in different ways of thinking.

    Sixth, we should pay attention to the sensor enterprises that are small in scale but have real intellectual property rights and core technology.
    For example, MCS technology in pressure sensor, optical fiber technology; electrochemical technology in gas sensor; mass sensor technology in flow sensor; basic material technology in temperature sensor; high-precision encoder technology in machine tool; of course, there are a variety of high-end requirements in military industry, which is in line with the overall requirements of China's high-quality development.
    It will also gradually reduce the differences in sensor technology and industry between our country and the developed countries.

     Finally, let's talk about the China Sensor Exhibition.
    The China Sensor Internet of things Industry Alliance, under the leadership of the Ministry of Industry and Information Technology and Shanghai, promotes the development of sensor technology and industry in China.
    Different sensor exhibitions are held in Shanghai and Shenzhen respectively. It is hoped that the sensor exhibition in Shanghai will be able to match the Sensor Expo of the United States, with emphasis on sensor technology seminars, technical discussions and exhibitions as auxiliary. It is hoped that the sensor exhibition in Shenzhen will be able to mark the Sendor + test of Germany, which will soon become the focus of global sensor exhibitions and conferences.
