In recent years, with the development of intelligent manufacturing, smart cities and other intelligent, intelligent industry, sensor industry as the basis for all wisdom, more and more attention from the public and government officials, the official media . CCTV, People's Daily, Xinhua, private tidbits and WeChat blogs of all kinds of self-media have a lot of sensor articles and news. As industry insiders, we feel both relieved and confused; our mood, sometimes passionate, sometimes anxious. Relieved is the former niche industry, subdivision of industry, has received attention and attention from all sides, confused is that most people do not understand the connotation and scope of the sensor; industry windfall came, we are passionate to do a great job, and strive to make due contributions to China's sensor industry; however, worried is that many local governments and media do not understand the sensor, and do not understand the basis of the region. A lot of flashy vision and slogans, in a way, no planning, no focus, low-level duplication of construction and copying all over the country. Will make China's sensor industry miss the opportunity for rapid development, towards copying foreign low-end technology, the route of mutual low-cost competition, which must be wary.

        Baoji, because there is China's first silicon piezoresistive pressure sensor, and decades of pressure sensor production history, while dozens of silicon pressure sensor companies are relatively concentrated, to build the western sensor base, to become the "sensor capital of China", the slogan and vision should be good, but how should be developed, should do more planning or thinking.

       Qingdao, is an important production base for household appliances in China, and "Goer Acoustics" in Qingdao's new investment, sniffed the sensor wisdom "smell", held several sessions of the Intelligent Sensor Forum, proposed to build " Northeast Asia sensor capital", ambitious, ambitious and earth-shaking. But the overall Qingdao sensor or smart sensor base is not satisfactory, sensor is a multi and scattered industries, need a large number of enterprises to support, I hope Qingdao on the way to "Northeast Asia sensor capital" to go well.

       Zhengzhou, as the largest gas sensor company in China, is the home of Hanwei Technology. For three consecutive years, we have spent millions of dollars to hold the "World Sensor Conference WSS", inviting Nobel Prize winners and most academicians to speak on stage and give advice. Has sounded the trumpet of intelligent sensors, also has a certain influence in the country, but also to establish a "sensing valley". The next five years, if Zhengzhou can emerge from the scale of five Hanwei technology, it should be said that great success.

       It is understood that China from north to south, from east to west have sensors intelligent sensors are planned. Guangzhou, Shenzhen, Hangzhou, Wenzhou, Jiaxing, Shanghai, Wuxi, Suzhou, Changzhou, Zhangjiagang, Nanjing, Xuzhou. Luoyang, Xinxiang, Harbin, Shenyang, Beijing, Taiyuan, Changsha, Wuhan, Xi'an, Chongqing. Due to the development of the Internet of Things, smart cities, smart manufacturing, many of the cities are included in the sensor although there is no clear sensor as the direction.

        I speak on different occasions "sensor" three Chinese characters, a word, not just to cover an industry. We speak of sensitive components: let's say, thermal components, photosensitive, gas-sensitive components, etc. belong to the components industry; we speak of MEMS sensors: for example, pressure sensors, gyroscopes, acceleration, etc. belong to the semiconductor industry or IC industry; we speak of photoelectric switches, proximity switches, etc. belong to the automation industry; we speak of pressure transmitters, temperature transmitters, flow sensors, most of which belong to the instrumentation industry We talk about pressure transmitters, temperature transmitters, flow sensors, most of which belong to the instrumentation industry; large radar, BeiDou navigation belongs to the aerospace industry. Now in China, 1000 so-called experts have 1000 sensor understanding, just like Shakespeare's "Hamlet". Remember, different principles, different physical forms of sensors belong to different industries, understanding, the industry is easier to have new ideas in investment or park construction.

         In fact, sensors, smart sensors and the Internet of Things are somehow as pervasive as "air" in all of our industries.

       For example, we are talking about the most pressure sensors. MEMS chip-level pressure sensors, narrow temperature range, low precision, a unit price of about $, mostly used in consumer electronics, belongs to the cell phone industry; MEMS + plastic package, a little higher precision pressure sensors used in medical devices such as sphygmomanometers, and belongs to the medical device industry; wide temperature range, a little higher precision MEMS pressure sensor wafers used in oil-filled cores, or silicon capacitors, single crystal silicon high-precision and high-stability pressure transmitter, and belongs to the instrumentation industry; good stability, environmental adaptability of the package structure used in the car pressure sensor, belongs to the automotive industry; higher accuracy, low temperature at -55 degrees or lower, high temperature at 150 degrees or higher, and belongs to the military or aerospace industry. In view of this, we can understand the same name for the pressure sensor, due to different industry applications, belonging to different industry categories.

        So local governments at all levels to engage in a variety of sensor parks, should pay attention to which industry or in which application to develop sensors and intelligent sensors, the development of their own strengths, strengths and weaknesses, the region's sensors positioned to make a good contribution to the development of the sensor industry nationwide.

       Sensor industry or industry or technology is wide enough that places should be able to develop according to their own basis, staggered. And this industry is not like the auto industry, and you are not like the solar photovoltaic industry. Never retrace the route of certain industries in China, swarming all over the low price competition, smashing each other's prices.

         Sensor industry has just taken off, the long march of ten thousand miles has just begun from Ruijin, our sensor road is heavy and a long way to go, I hope the industry can recognize the reality of the rapid development of their own planning and route for China's sensor industry to the world, beyond Europe and the United States to make efforts. 10 years later, Europe and the United States should also learn from China's advanced sensor technology, China's high-end sensor technology and product output To Europe and the United States and other developed countries, this may be the responsibility of our generation of sensor people.

       When the wind comes, we should not become a "pig" in the wind, but should navigate independently on the wind and waves, and sail towards the ideal shore.
