After returning from Germany in less than a month, I am leaving for London today to exhibit at the FARNBOROUGH AIRSHOW and to visit a few customers in England. The first flight from Xi'an to Beijing, CA1230, was delayed. I hope there will be no more delays in this summer rainstorm, and the connecting time to Beijing is only three and a half hours, so if there are any delays, I will not be able to catch the next trip.
Yesterday afternoon, Xi'an Hi-tech Zone Venture R & D Park organized by the entrepreneurial monthly talk (Internet of Things special session), of course, the Internet of Things can not be separated from the sensor. At the meeting, more than a dozen enterprises talked about the current status of the enterprise problems and difficulties. In general, the current international and domestic economic situation is not very good, most of the business difficulties have become the norm. Some companies, the domestic is too voluminous, want to export and difficult to start; some companies have a single and no cash support; some support for the construction of science and technology companies, due to the real estate drag stagnation; some of the Internet of Things company technology systems are readily available to support the construction of smart cities, the government has no funds to support these new infrastructures, the company is struggling; really: every family has a difficult to read a scripture, so do the enterprises. But we all refuse to lie flat, and strive for greater opportunities.
IoT needs more sensors, more sensors that weren't there before, and that's the key point to solving the existing problem.
Last week, we had a customer who needed a sensor to distinguish between water and sediment in a city sewer , that is, when the sensor comes into contact with water, it is one state output, and when it comes into contact with sediment, it is another output. I sent out the demand in my circle of friends . Gu thinks capacitive sensors may also be able to solve this problem ?

The Guangzhou Wechat-friends suggested using density sensors, because the density of water and sand is not the same! However, the density of sand and mud is not uniform, and the density sensor is also in the state of uniform density detection, and the cost is also relatively high.
Baoji Wechat-friends suggested that the use of a long strip of ceramic piezoelectric vibration plate, by measuring the vibration of different to test the difference between sand and water, but there is no ready-made products to do the test, as well as how to solve the problem of waterproof?
Shanghai's netizens believe that their capacitive sensors do the best, but taking into account the capacitive properties of water, that the next day, to find their technical staff to ask for advice. As a result, wait until the next day the answer is: No, not feasible!
Jiangsu's netizens said that their capacitive sensors, whether switching or continuous, should be able to, the results of the phone, the application scenarios to speak after the defeat.
Nanjing users said, can use high-precision ceramic pressure sensors to distinguish between water and sediment pressure? But whether the sediment can be accurately measured, its pressure can be stabilized at a certain value, it is also difficult to conclude?

The Sichuan Wechat-friends suggested a mechanical vibration sensor, but the installation in the city underground pipeline is a problem? Whether the vibration can be measured also remains to be tested.
Colleagues in the company suggested the use of thermal flow sensor detection, there are also installation problems, cost problems, power consumption problems.
Sensors in daily life is easy to say, to do a good job is not an easy task.
In the end, what kind of sensor is appropriate? Valley brother in the turn of the circle of friends, some people in the advertisement: capacitive level sensors, tuning fork sensors!
Good! Tuning fork sensor, should be able to try! This Beijing branch in Xi'an, Mr. Li, the next day to us to do an experiment, a better verification of this problem!
To be precise, more advertisements in the circle of friends is still useful, not to say that there is not much use!
We expect this solution to pass our customer's test and open up a new market for iot sensors.
Our lives, our production will encounter a variety of different scenarios, in the era of the Internet of Things, in the era of digitalization wave everywhere, each segment of the solution will have a blue sky, or a colorful cloud.
Similarly, many problems in life can be solved by many different technologies of sensors. This example shows us that in the existing coverage of various sensor technologies. If you have mastered a variety of sensor technology, you have mastered the core of the Internet of Things, the underlying perception of the program.
We've been sitting in the cabin in Xi'an for over an hour now due to the hailstorm in Beijing and still don't know when we'll be able to take off. Looking forward to not delaying my next trip to London at 2:30pm.
I can't help it! Still don't know when to wait?
