The presence of radar sensor linkage light sensor makes the wardrobe smarter

The presence of radar sensor linkage light sensing makes the wardrobe more intelligent. Radar has become a research hotspot at home and abroad because it has all-weather, long-distance and non-contact detection capabilities, and can detect targets behind obstacles. By extracting the human body information from the radar echo, the human body feature extraction algorithm of the radar echo is realized, which is the key technology to realize the human body detection.

Due to the many advantages of radar in human detection, radar human detection technology has become a hot research direction today, and the role of radar human detection in civil applications is becoming more and more obvious. The Doppler effect is a phenomenon in which the frequency of a signal changes as it moves relative to the radial direction between the transmitter and receiver. Radar echoes contain rich physical information, including human motion characteristics, human fretting characteristics, etc.

The presence of radar sensors can realize non-contact detection, which has inherent advantages, and can link lights to detect targets in the room, which has obvious practicality in smart homes, hotels, housing, etc. Smart hotels can use presence radar sensors to detect human bodies and realize intelligent control applications. Real-time sensing of human presence is convenient for managers to respond at any time. This radar solution is not only suitable for hotels, but also for home care, hospitals, nursing homes and other occasions.

In a hotel, when a guest opens the door, the radar senses the presence of a human body and will link the air conditioner in the room, which will automatically turn on, the lights will also be automatically turned on, the curtains will slowly open, and a wonderful concert will sound immediately. . . For the convenience of customers staying in the hotel. In order to increase the guest's check-in experience, more and more people are using sensors instead of traditional mechanical controls to improve check-in satisfaction and efficient management of hotels.

The combination of radar sensors and lights makes the wardrobe in the room more intelligent and convenient. In the perception layer of the Internet of Things, the radar human sensor undoubtedly plays an indispensable role in realizing the intelligent scene of the Internet of Things. With the help of sensors, people can detect the movement and movement of objects, so as to realize functions such as smart lighting, smart home, and smart scene definition, which are widely used in smart lighting, smart home, smart home appliances, smart security and other fields.

When the wardrobe is opened, it is embarrassing to get up early to go to work to find clothes. Clothes are plentiful and dark, and a presence radar sensor is installed at the top of the wardrobe. When people open the door, it will automatically light up, so you can see what you are wearing at a glance, making it easier and faster to go out without having to manually open the door, and then walk around to turn off the light when you leave.

The revolution of new technology has promoted the development of innovation and upgrading of lighting products, the Internet of Things and 5G technology, and led the further development of the lighting industry to the intelligent industry. In the intelligent era, wardrobe lights have also been upgraded to radar sensor lights.

The existing radar sensor integrates a 32-bit high-performance MCU, and a single chip directly outputs the induction control signal. Powerful performance, rich algorithms, and strong scalability, suitable for scenarios with high performance requirements. Based on human breath detection, it supports standard UART interface and can be connected to other major controllers or sensors. Through intelligent means such as radar sensing, the smart wardrobe light can be turned on, which is convenient and labor-saving, and brings convenience to people's lives. When someone appears in front of the wardrobe, the light can be automatically turned on, and the light will be automatically turned off when leaving, which is efficient, intelligent, convenient and practical.
