Lighting radar sensing stationary body sensing sensors: A new chapter in the smart home

I. Introduction

With the continuous development of science and technology, people's requirements for quality of life are gradually improving. In this era of information and intelligence, smart home has become a necessary choice for people to pursue convenient and comfortable life. Among them, as a new type of smart home equipment, the lighting radar sensor is gradually entering our lives, bringing unprecedented experience to our daily life. This paper will introduce the principle, advantages and application of lighting radar sensor in smart home.

Second, the working principle of lighting radar induction stationary human body sensor

The illumination radar sensor is a kind of intelligent sensor based on millimeter wave radar technology. It can accurately detect the presence of the human body or other objects by transmitting high-frequency electromagnetic waves and receiving the reflected signals. Compared with traditional infrared and ultrasonic sensors, millimeter wave radar has higher resolution and stronger anti-interference ability, and can better adapt to various environments.

Third, the advantages of lighting radar induction stationary human sensor

High precision: Millimeter wave radar has a high frequency and bandwidth, which can achieve high precision detection. In the smart home, it can accurately detect the position and movement of the human body, so as to achieve intelligent control of lamps, curtains and other equipment.

Strong anti-interference ability: due to the high frequency of millimeter wave radar, it can effectively avoid various interference signals, such as sunlight and electromagnetic fields. Therefore, in a complex home environment, it can still maintain a high detection accuracy.

Energy saving and environmental protection: Compared with traditional infrared, ultrasonic and other sensors, MMwave radar has lower power consumption, and does not contain harmful substances, which is more environmental protection and energy saving.

Easy installation: The lighting radar induction stationary human body sensor is generally connected wirelessly, without complicated wiring, and the installation is very simple.

Fourth, the application of lighting radar induction stationary human body sensor in smart home

Intelligent lighting: Through the linkage with lighting equipment, when the human body enters the room, the light automatically lights up; When the human body leaves the room, the lights automatically go out. This intelligent lighting control method can not only save energy, but also improve the comfort of life.

Smart curtain: When the light is strong in the morning, the smart curtain will automatically close; At night or when the light is low, the smart curtain will automatically open. This automatic curtain control method can not only avoid excessive sunlight on the room, but also effectively protect privacy.

Intelligent home appliances: Through the linkage with all kinds of home appliances, it can achieve a variety of intelligent control methods such as one-button control and voice control. For example, when you go home in the evening, a sentence "Xiao Rui, I am back" can automatically turn on the lighting, air conditioning and other equipment in the living room, so that you can enjoy a comfortable home.

Security monitoring: Because millimeter wave radar can detect tiny movements such as breathing and heartbeat of the human body, it can also be applied to the field of security monitoring. For example, a millimeter wave radar sensor installed in the bedroom can monitor the situation in the home when the person is not at home, and notify the owner immediately if an abnormal situation occurs.

V. Summary

As an important part of smart home, the lighting radar sensor is changing our way of life with its high precision, strong anti-interference ability, energy saving and environmental protection, easy installation and many other advantages. With the continuous development of science and technology, we have reason to believe that this intelligent lifestyle will become more and more popular, bringing more convenience and comfort to our lives.
