Millimetre wave radar has been widely used in automobiles due to its small size, high spatial resolution, strong penetration and anti-interference capability. But in fact, due to the high resolution of millimetre wave radar, it also has a strong application advantage in the field of human presence perception, and can even remotely measure human heart rate and respiratory rate.

Studies have shown that heart rate and breathing rate can quickly diagnose deadly diseases such as sleep apnea and complications of sudden infant death, all of which have different breathing patterns. People with high or low resting heart rates also have a higher chance of developing certain diseases. Therefore, in nursing homes or hospitals, millimetre wave radar can be used to check the vital signs of patients or elderly people, so that caregivers can be alerted to any abnormalities in a timely manner.


Of course, in terms of characteristics, millimetre wave radar is actually very suitable for the presence of human body sensors in the smart home. In some recent exhibitions, the reporter also saw many millimetre wave radar manufacturers have products for smart home. However, from the point of view of their market performance, although they are promoting smart home applications, but in fact, the current market situation is not ideal.


Shenzhen, a millimetre-wave radar board manufacturer Audemars Piguet told reporters that its products are mainly used in intelligent car parks and intelligent building scenes, such as the gate 79GHz collision radar, parking space awareness radar and human presence awareness radar. Just two months ago, the company completed a round of financing, investors from the domestic first-line home appliance giant A funds.


Reporters learned that in the field of smart home,they cooperate with graffiti wisdom, join graffiti wisdom ecosystem. The human sensory radar products can be linked with other products through the ecological platform.However,the staff of the current manufacturer said that despite the availability of many smart home products but in fact, the application of smart home is still very little, and now the company's business is mainly in car parks,offices and other scenes. Installing millimetre wave radar in offices or indoor corridors can achieve the effect of switching off the lights when people walk, which to a certain extent can save companies a lot of energy. However, in the c-suite smart home, millimetre wave radar still has some problems to be solved.


Firstly, compared with traditional infrared or microwave body sensors,millimetre wave radar has high power consumption and cannot be powered by batteries. Nowadays, smart homes are generally more in the form of post-installation, so all smart homes in the market come with human body sensors, and most of them are in the form of battery power supply, which is convenient for installation. However, the installation of millimetre wave radar requires wiring in advance and needs to be planned before the renovation, which is difficult to do for most homes. If you use direct communication, then the range of use and the scene will be greatly reduced. This is why it is now used in commercial areas such as hotels and offices.


The second is the cost, a millimetre wave radar board manufacturer proposed another application scenario, that is, the integration of air-conditioning, fans and other products to achieve self-starting and self-shutdown. However, for home appliance manufacturers, the cost is quite sensitive. Although the current price of 79GHz body sensor radar, Shenzhen Audemars Piguet Circuit can achieve less than 200, but this is far from enough for home appliance manufacturers.


However,judging from the strength of investment from home appliance manufacturers to millimetre wave radar board manufacturers, the industry is still relatively optimistic, at least with regard to the prospect of millimetre wave radar's application in the smart home. It is expected that millimetre wave radar will find its place in the consumer field in the future.
