Two extensions of human senses-sensors and the Internet of Things
The widespread application of sensors and the Internet of Things has driven the development of human society. The term sensor is authoritatively interpreted as: a sensor is a detection device that can sense the measured information, and can transform the sensed information into electrical signals or other required forms of information output according to a certain rule , To meet the requirements of information transmission, processing, storage, display, recording and control. This kind of explanation is troublesome and difficult to understand. Compared with this, the editor prefers to regard the sensor as an extension of the five senses. Electric features-sensor classification The sensor is an extension of the human body's features and an upgraded version of the human senses. In order to obtain information from the outside world, people must rely on sensory organs such as ears, nose, and mouth. However, the more rapid technological advancement, the more people will find that human abilities have limits. In order to cope with this situation, sensors have to be used to monitor increasingly large environmental factors. Through the application of sensors, environmental factors that people cannot judge can be expressed in the form of data more accurately and clearly. According to the specific function and practical application of the sensor, the sensor is divided into seven categories: resistance type, resistance strain type, piezoresistive type, variable frequency power, thermal resistance, laser, and Hall element sensors. Among these types of sensors, most of the functions of the sensors can correspond to the human sensory organs.

The information content and information format captured by different types of sensors are different, and the data obtained by the sensors is real-time. Collect environmental information periodically at a certain frequency and update the data continuously. However, there is no sensor based on the Internet of Things. Monitoring data can only be displayed on the spot. The devices are independent of each other. The staff records the data by handwriting and cannot systematically analyze the data. The function of the Internet of Things is to connect all the sensors in series and conduct a comprehensive analysis of the uploaded data. The Internet of Things is undoubtedly an epoch-making invention for various industries, allowing sensors that were originally only used in industry to auxiliary functions to spread all around life. Nervous system-Internet of Things If the Internet of Things is the nervous system, then the sensor is the nerve ending of the Internet of Things. It is not only the core element for humans to perceive the outside world, but also the core element for all things to perceive each other. , The more technology develops, the higher the sensitivity of the sensor. The existence and development of sensors give objects the sense of touch, taste and smell, and make objects slowly become alive. Large-scale deployment and application of various sensors, covering areas including smart industry, weather monitoring, smart home, dust monitoring, smart medical, etc. This is equivalent to arranging a nervous system for the world. With this nervous system, the whole world is of course more spiritual. Sensor technology, RFID tags, and embedded system technology are the three key technologies to realize the Internet of Things! These big data are managed through the Internet, and then through the super powerful central computer group, such as cloud computing, real-time management of people, machines, and equipment. This realizes the integration of humans and physical systems, so that human production and life can be more refined, accurate and dynamic, and reach the intelligent state of unity of all things. Currently, the application of sensor technology and the Internet of Things plays an important role in economic development and social progress. Countries all over the world attach great importance to the development of this field. Sensor technology based on the Internet of Things will undoubtedly reach a qualitative leap and a new level.
