    I. Introduction


    With the rapid development of science and technology, human sensors have become an indispensable part of our lives. Whether in smart homes, security systems, or healthcare, body sensors play an important role. In the field of advertising machine, microwave radar sensor, as an advanced human body sensing technology, is gradually receiving extensive attention and application. This paper will deeply discuss the working principle of human body sensor, as well as the advantages and application scenarios of microwave radar sensor for advertising machine.

    Second, the working principle of the human body sensor


    The human body sensor is a type of sensor based on microelectronic technology that is able to detect small changes in the surrounding environment in a non-contact manner. It mainly uses electromagnetic waves such as infrared and microwave waves to carry out non-destructive testing on the human body, so as to perceive the existence and motion of the human body.


    Among them, infrared body sensor is a common one. It receives infrared radiation from the human body and converts it into electrical signal output. This sensor has high sensitivity and response speed, but the disadvantage is that it is prone to misjudgment when detecting moving objects.


    Microwave radar sensors are another common type of human sensors. It uses microwave pulses to scan the surrounding environment, and determines the position and motion of objects by analyzing the reflected microwave signals. The advantage of this sensor is that it has strong penetration and anti-interference ability, and can work normally in a more complex environment.


    Three, the advantages of microwave radar sensor advertising machine


    In the field of advertising machines, microwave radar sensors have the following advantages:


    High sensitivity: Microwave radar sensors can effectively detect small movements and position changes of the human body, so as to display more accurate interactive effects on the advertising machine.


    Strong anti-interference ability: in complex environments, such as noisy public places with many people, microwave radar sensors can effectively suppress interference signals and ensure the normal operation of advertising machines.


    Intelligent recognition: The microwave radar sensor can analyze the reflected signal to determine the movement trajectory and behavior pattern of the human body, so as to display more personalized interactive content on the advertising machine.


    Energy saving and environmental protection: Microwave radar sensors have a low energy consumption in operation, while not requiring the use of any chemicals, so the impact on the environment is small.


    Fourth, the application scenario of microwave radar sensor of advertising machine


    Shopping guide system: In the shopping mall, the microwave radar sensor of the advertising machine can detect the movement track and behavior pattern of customers, and recommend suitable products for customers to improve the shopping experience and sales in the mall.


    Smart home system: In the smart home system, the microwave radar sensor of the advertising machine can be linked with other smart devices to achieve automatic control and personalized customization of the smart home.


    Museum guide system: In the museum, the microwave radar sensor of the advertising machine can provide more personalized and accurate guide services for tourists by detecting the location and movement trajectory of tourists.


    V. Summary


    With the continuous development of science and technology, human body sensors are more and more widely used in various fields. As an advanced human body sensing technology, microwave radar sensor of advertising machine has the advantages of high sensitivity, strong anti-interference ability, intelligent recognition and so on. It has a wide range of application prospects in shopping mall guide, smart home, health care, museum guide and other fields. It is believed that in the near future, human sensor technology will play an important role in more fields, making our lives more convenient, comfortable and safe.
