Static detection of human body microwave sensor smart hotel application

Static detection of human body microwave sensor smart hotel application, in smart life, we often encounter a phenomenon, when we are relatively still, the automatic sensor light will automatically turn off, when we do the second action, the light will continue to light, This is a common phenomenon, the problem is that the sensor cannot detect the stationary state of the human body.

Human body microwave sensors are widely used to determine whether the human body has life activities. The problem with traditional human sensors is that if the user remains in a fixed position for a long time, the human sensor cannot sense the person.

Therefore, when people watch TV in the bedroom, read in the study or go to the toilet in the bathroom, the sensor of the human body does not sense the human body, resulting in the lights off or other problems.

Our company has developed a microwave sensor for static detection of human body, which can also sense the human body when the human body is stationary. The radar sensor is small in size and low in power consumption. It can be hidden and installed through the plastic shell, and it is beautiful and elegant. A moving living body can be detected, and a stationary or sleeping human body can also be detected. It can effectively solve the problems in current smart hotel and smart home scenarios, such as insensitivity, inaccuracy, misjudgment, etc.

The static detection human body microwave sensor can not only sense the dynamic of the human body, but also sense the static human body. In order to make up for the defect that the sensor can only detect the dynamic human body, it accurately senses the presence of the human. On the basis of the Doppler effect, fixed frequency directional transmit and receive antennas are used, and chip integration technology is used to combine with microwave antennas.

The static detection human body microwave sensor has the functions of small size, high sensitivity, stability, clutter, high-order harmonic suppression, etc., and the internal modularization integrates the functions of intermediate frequency demodulation, signal amplification, digital processing, light intensity detection, timing and other functions. Detects the breathing activity of the human body and can be used to monitor vital signs.

The static detection human microwave sensor uses the presence signal from radar sensing to control the light on. When people enter the door, the lights are on, and when people go, the lights are off. Compared with ordinary human body detectors, the sensing range of radar sensors is more standardized and controllable, and the performance is also very ideal.

In the perception layer of the Internet of Things, the microwave radar human sensor undoubtedly plays an indispensable role in the realization of intelligent hotel scenarios. Therefore, it is widely used in smart lighting, smart home, smart hotels and other fields. Through the microwave radar sensor, the movement of objects can be detected, so as to realize functions such as people coming to light, intelligent linkage, and scene definition.

For example, when the customer pushes the door to enter, the static detection human body microwave sensor detects that someone enters, the real-time linkage control light is on, the curtains are slowly opened, the air conditioner is turned on, and the smart speaker plays the welcome language, etc.

With its unique advantages, it can help hotels attract attention, increase exposure, and form a differentiated core competitive advantage. When the guest opens the door, the room is automatically powered. Configure to automatically turn on lights, open curtains, turn on TV, play greetings, etc. as needed. After check-out, the room will automatically shut down and it can be configured for immediate power outage or no power outage for a period of time.

Through the hotel platform, the static detection human microwave sensor can check whether there is anyone in the room, which can easily manage the actual check-in situation, and can also dynamically guide the cleaning of the room. Monitor the unmanned status of the room through sensors, determine whether the settlement has been settled, and remind the hotel front desk or manager.

Contactless check-in can improve hotels’ resilience to risk. The application of static detection human microwave sensor technology in smart hotels further accelerates the normal operation of hotel services, and realizes functions such as card-free check-in, card-free electricity withdrawal, and automatic early warning. While saving costs, it effectively improves the hotel's anti-risk ability, which not only reduces the problems of hotel occupants, but also effectively improves the hotel's anti-risk ability and saves costs.
