Breathing Presence Radar Sensor Smart Home Human Sensing Applications

Respiration presence radar sensor smart home human body induction detection application, due to the existence of human life activities (movement, breathing, etc.), human life parameters are detected by microwave in the form of pulses, so that the callback pulse sequence reflected by the human body changes. Through demodulation, integration, amplification, filtering and other processing, it is input into the microcomputer system for data processing and analysis, and the data parameters of the human body can be obtained by using the breathing presence radar sensor.

When the human body is in a state of static breathing, radar sensors can identify the heartbeat and breathing movements of the chest and abdomen, and accurately identify such small movements. It is suitable for signal detection in cars, offices, conference rooms, toilets, hospitals and other scenarios. The breathing presence radar sensor is composed of a high-gain microstrip antenna, a signal processing circuit, an algorithm and a circuit, an algorithm and an integrated chip. The on-board integrated IF demodulation, spectral energy analysis, signal amplification and digital processing technologies can be adjusted according to customer needs. It can be used in smart hotels, smart elderly care, smart lighting, smart security, smart home and other fields to detect vital signs such as human walking, running and other major movements, shaking their heads, swinging arms, and human breathing.

Radar can penetrate plastics, wall panels, clothing and other specific materials and is immune to rain, fog, dust, snow and other environmental conditions. Millimeter waves can not only detect objects, they can provide distance, speed and angle of objects. At the same time, the application of radar in daily life can be seen everywhere.

The breathing presence radar sensor technology is combined with applications such as home Internet of Things, medical care, elderly care, and intelligent services to form vertical applications. Radar products are not limited by light and privacy. The presence of a person can be determined by measuring breathing, and thanks to the permeability of radar, it can be sensed through glass and wood panels.

The advancement of technology has made our lives easier and easier, from ordinary switches on the wall, smart panels, to mobile phone applications, to voice control. There is a human body sensing radar in the sensor, which makes the intelligence more timely, efficient and considerate. When you bring dinner from the kitchen to the dining room, you don't have to free your hands to turn on the lights. The Breath Presence radar sensor senses you're coming and can automatically turn on the lights for you.

Breathing human radar sensors are very capable. It can accurately control the perception range and ensure that the perception areas of adjacent spaces, such as bedrooms and cloakrooms, do not overlap, which is more practical, energy-saving and environmentally friendly. It also monitors the security status of the home at any time in leave-home mode and sleep mode. When you're traveling outside and working overtime in the middle of the night, it will immediately send you a warning message via the mobile app if it monitors outsiders breaking into your home.

Breathing presence radar sensor has strong perception sensitivity, unique penetration function, can be used to measure distance, limit distance, set detection area, identify and isolate small movements, can penetrate plastic and clothing, and even lightweight building materials. On the basis of the Doppler frequency-modulated continuous wave radar system, the static perception and biological perception of human biological movement and biological perception are realized. Suitable for home, hotel, office, car, hospital monitoring and other places.

Many elderly people need to perform nursing monitoring on patients, and use non-contact vital sign monitoring. This monitoring system can provide sleep status, bed status detection, etc., providing better information for nighttime nursing staff or nurses and improving nursing efficiency. Respiratory presence radar sensor can assist living and patient monitoring, such as sitting too long, sleepwalking, sleep/wake measurement, bed detection, patient rollover detection, prolonged stay in the bathroom, etc. can be detected, suitable for assisted living, nursing homes, hospitals , and can alert employees or relatives.

Human body induction radar is based on Doppler frequency modulation continuous wave radar system, which realizes static perception and biological perception of human biological movement. Suitable for home, hotel, office and other places. The non-contact breathing presence radar sensor detection device does not need to be worn by the human body, has a friendly user interface, and is a new detection method. Radar-based vital sign detection does not require contact with the human body, is not easily affected by the surrounding environment, and has strong penetrating power.

Breathing presence radar sensor The human body has sensing technology, which can effectively distinguish between static human body and fretting breathing, and effectively avoid the interference of surrounding movements. Radar sensor IoT, health care, community services and other applications are combined to form vertical applications. I hope this technology can help intelligent applications of IoT. All industries are in a critical period of digital transformation, and new technologies may become new infrastructure.
