Yesterday was still a busy day. In the morning, I attended the 2023 meeting of Shaanxi Instrument and Watch Society and the establishment meeting of the Industrial Internet of Things Special Committee in Xi'an High tech Zone, and shared a special report at the meeting.

       The content mainly introduces the latest typical applications of the Internet of Things, especially in the field of intelligent manufacturing. A brief overview of the Shaanxi Internet of Things and the current problems and development trends in China's Internet of Things, as observed by Gu Ge himself.

      After lunch, accompanied some experts from Shaanxi Instrument and Watch Society to visit Xi'an Zhongxing Measurement and Control Company to understand the company's work performance in the field of Internet of Things. Wei Lifeng, the director of the company's Internet of Things market, emphasized the company's smart manhole cover monitoring system and other aspects the comprehensive solution for smart blocks, especially the comprehensive intelligent monitoring system for urban waterlogging, is introduced.

         At around 3 pm, I rushed to Xi'an Jiaotong University to attend the summary meeting of the "White Paper on the Development of the Baoji Sensor Industry" organized by the Sensor Branch of the China Instrument and Meter Association and the Baoji Municipal Government. I especially hope that Shaanxi Baoji can seize the opportunity in the current Chinese sensor industry, where there is a fierce competition among feudal lords. Firstly, focus on industrial pressure sensors and strive to be among the top in China; Secondly, investment promotion should be coordinated with Xi'an for development, with research and development in Xi'an and industries in Baoji; Thirdly, investment promotion and support policies should focus on key areas and not be scattered; Fourthly, it is important to truly grasp sensors, rather than just writing articles and creating buzz.

      At 11:23 pm, I took the T8 Green Skin Express train again from Xi'an to Beijing. As a native of Xi'an, after the expansion and renovation of Xi'an Railway Station, it is still the first time I have departed from Xi'an Station. Compared to the previous railway station, it is truly surprising and stunning, to the point where my chin drops.

     In my impression, the express soft sleeper is also a good choice. Rest overnight in the car without delaying the next day's trip to Beijing. However, the feelings from over a decade ago seemed to suddenly change last night, and the beautiful memories suddenly shattered. Firstly, the ups and downs of the train make it difficult for people to rest; Secondly, the private rooms seem smaller than before, with a bad odor and poor air quality; Thirdly, there is no power socket in the private room, and there is no power bank borrowed.

     Gu Ge forgot to bring a portable power supply because he had been busy all day and his phone's battery capacity was not much left. I was worried about using my phone the next day, so I didn't dare to watch WeChat, take photos, play videos, let alone write a note about "Small Talk about Sensor While Travelling" in my spare time. So I had to turn off my phone and save a small amount of battery.

     Sincerely sighing, the development of the times is really fast. A few thousand yuan smartphone has thrown tens of millions of express soft sleeper trains next door.

     Today, while taking a taxi in Beijing. I found that the driver had placed a small umbrella on her phone to block the sunlight and make it easier to see the navigation map. Can this umbrella become a small object for cars in the future?

     Now, the phone can be charged, and this issue of "Small Talk about Sensor While Travelling" can only be written on the high-speed train returning from Beijing to Xi'an. The G665 train has just passed through Hebi, Henan, and I have some leisure time. Recently, many people have talked to me about the definition of sensors in the era of the Internet of Things; Many netizens also ask how to choose the appropriate sensor in the era of the Internet of Things? People often ask me if I have a pressure sensor? Or send me a photo of a pressure sensor from abroad and ask if I have a domestic substitute? This question is actually difficult to answer. There are no basic parameters, I have to answer you, right? There may be many factors that are not suitable. I have to say no, our company produces hundreds of thousands of pressure sensors every year, with unit prices ranging from ten dollars to several thousand dollars. Sometimes WeChat cannot answer immediately, and WeChat users may still have comments or complaints.

      So, I'll make a table today. Tell everyone how to choose wireless smart sensors in the era of the Internet of Things, or the many factors to consider when choosing wireless smart sensors, mainly in terms of technology selection.

     I hope this table is useful, beneficial, and helpful for friends who choose sensors in the era of the Internet of Things.

     In the era of the Internet of Things, what is a generalized sensor or, more broadly, perception technology? Perhaps no one has expressed it well, university professors have limited exposure to reality in applications, and IoT practitioners have no time to pursue it. In recent years, Gu Ge has been both a practitioner of the Internet of Things and an explorer of the theory of the Internet of Things. Therefore, boldly promoting his thoughts in different places is not comprehensive, only hoping to be close to reality.

     Welcome friends to like or criticize, and together we will improve the definition or category of generalized sensors in the era of the Internet of Things.
