At present, microwave detection is widely used to detect the presence of the body in the magnetic induction region. Moreover, radar has large magnetic induction Angle of view, fast reaction speed, material characteristics of non-metallic materials, strong environmental adaptability, and is not affected by natural environment, ambient temperature, dust and other factors. In the perception layer of the Internet of Things, AOZ1210AI microwave radar human body sensor undoubtedly realizes this indispensable function, and is widely used in intelligent lighting system, intelligent home system, intelligent hotel and other industries.
In our daily life, we often come across a situation. When we are still, the human body sensor light may misjudge, causing the light to go out. When we do the second movement, the light will be illuminated. This is often the case with conventional sensors, which means that the resting state of the body cannot be accurately detected.
At present, microwave detection is widely used to detect the presence of the body in the magnetic induction region. However, for the traditional body with magnetic induction, it is difficult to accurately detect the body in static data. Clients often remain in the same position for long periods of time, making it difficult for human sensors to detect a person's presence.
Therefore, when we are watching TV dramas in the living room or reading books in the small study, when the traditional body has magnetic induction, every once in a while, a stationary body will occur which cannot be detected, causing the lights to go out.
However, if the body has microwave magnetic induction, it will not make false judgments about static data objects. Microwave radar has high detection accuracy, fast reaction speed, low energy consumption and strong environmental adaptability. It can also be easily assembled using non-metallic chemicals. Microwaves in the body can detect not only moving objects, but also stationary or sleeping bodies. Effectively deal with the traditional body magnetic induction failure, inaccurate, wrong judgment or missed judgment.
According to the basic principle of Doppler, the body has microwave magnetic induction, according to send radio waves to the overall target and receive its radar echo, so as to obtain the object spacing, direction, speed, Angle of view and other relevant information. Moreover, radar has large magnetic induction Angle of view, fast reaction speed, material characteristics of non-metallic materials, strong environmental adaptability, and is not affected by natural environment, ambient temperature, dust and other factors.
Microwave magnetic induction exists in the body, using the radar magnetic induction from the data signal to adjust the light on. For example, when a person walks into the small study, the light will flicker and when we get rid of it, the light will go out. Compared with traditional body sensors, radar sensors have more controlled detection range and more ideal characteristics.
In the perception layer of the Internet of Things, microwave radar human body sensor undoubtedly realizes this indispensable function, and is widely used in intelligent lighting system, intelligent home system, intelligent hotel and other industries. According to the magnetic induction of microwave radar to measure the movement of objects, so as to achieve a variety of intelligent linkage, scene definition.
For example, when a customer pulls the door in, his body has microwaves. When he noticed someone entering, the interlock control lights immediately came on and the curtain gradually opened. At the same time, the central air conditioning will be turned on and adjusted to the optimum temperature.
By virtue of their personal strengths, they can be applied to hotels to help hotels and restaurants attract people's attention, enhance the customer experience and leave a deep impression on the customer. When the customer opens the door, the room's automatic power supply system automatically turns on the lighting effect, opens the curtains, turns on the TV, and starts the central air conditioning. After the rent is returned, the lights, curtains, TV and air conditioning in the room will be automatically turned off, and the power supply in the room will be automatically turned off.
At the same time, in the case of not violating the personal privacy of customers, it can also detect whether there is someone in the house, convenient for the hotel staff to quickly grasp the specific situation of the hotel restaurant, dynamic guidance of bedroom cleaning work.
This can not only reduce the hotel restaurant personnel manipulation, but also reduce the hotel labor costs, effectively bring risk to the hotel.
