Smart home millimeter wave radar module applications improve the quality of life, and sensors are often used to sense various states of the environment, such as temperature, humidity, or motion. Combined with bluetooth or bluetooth. Wireless technology sensors such as Wi-Fi are widely used in homes and businesses, opening up a very promising market in the electronics industry, especially in the field of IoT.

Smart home millimeter-wave radar modules improve quality of life

The development of sensors has provided many new technologies for improving environmental monitoring, and millimeter-wave radar is one of them. With this new sensing solution, applications for detecting, locating and tracking people, animals or moving objects will be revolutionized. Millimeter-wave radar can quickly detect the location of nearby targets, regardless of the surrounding environment.

As a non-contact sensing technology, millimeter wave radar modules can be used to detect objects and provide distance, speed and angle information of objects. In addition, millimeter waves can penetrate plastics, wall panels and clothing and are not affected by environmental conditions such as rain, fog, dust and snow. Therefore, millimeter-wave radars are increasingly used in security monitoring, smart office, smart home, and industrial manufacturing.


Introducing the millimeter-wave radar module technology into the field of video surveillance, combined with the visualization advantages of multiple types of cameras, the "video + radar" linkage application solution of the millimeter-wave radar technology can be launched. Compared with traditional head monitoring, it can fully make up for the shortcomings of video monitoring, such as different light, smog blocking the line of sight, strong wind affecting monitoring, bad weather, inaccurate visiting at night, etc.


Human detection will be one of the target markets for mmWave radar. Millimeter-wave radar has many advantages over current infrared and ultrasonic sensors. Millimeter wave radars are less sensitive to ambient temperature or the surrounding environment. These seemingly smart sensors, traditional passive infrared (PIR), do not work well in real life. Sensors based on millimeter wave radar technology provide greater precision for lighting or air conditioning control in smart buildings/homes. Combining this with video can greatly reduce detection errors in the field of IP cameras.


The smart home millimeter wave radar module can output intrusion target data in real time, and track and shoot with the camera. Actively warn the intrusion target, track, record, capture and identify multiple targets in real time to achieve the effect of comprehensive control. In addition to community monitoring applications, the application scheme of millimeter wave radar module technology and video surveillance linkage is also suitable for peripheral protection and important site protection such as airports, border defenses, energy pipelines, and important core areas, with higher recognition rate and lower error rate. reporting service.


At the critical moment of epidemic prevention, camera-based AI technology can indeed help us reduce direct or indirect contact in our daily work. At the same time, the use of AI technology also improves the experience and utilization of office space, but the widespread use of cameras also brings A relatively large hidden danger, that is, how to protect personal privacy? Especially in some non-public or semi-public places, such as employee office areas, conference rooms, toilets, etc. Compared with the camera, the big advantage of the smart home millimeter wave radar module is that it does not involve privacy leakage, its appearance has no disturbing lens design, and more importantly, the radar data information is completely anonymous, in line with the requirements of relevant privacy regulations, available For more office scenarios that are not suitable for deploying cameras.


Compared with AI millimeter-wave radar, it also has beneficial advantages in camera technology privacy. Since the radar identification processing is basically completed on the local device side, and there is very little cloud data uploaded to the background, it is only to identify personnel positions, trajectory information or statistical processed information, so the network bandwidth and cloud resources of the entire IoT system are very limited. , which can help enterprises greatly reduce the operating cost of the system.


In the field of pension households, multi-directional perception has become particularly important. It is necessary to ensure the normality of physiological detection data such as respiratory data and sleep quality of the elderly at home in real time. In addition, at present, in the smart home, the protection of personal privacy has gradually become a rigid demand, but it has also become a pain point, and technological breakthroughs are urgently needed to fill the gap. Millimeter wave radar products are not limited by light and privacy. They can judge whether there is a person by measuring physiological breathing, but they can also judge the physiological state of the elderly by measuring breathing and heartbeat. They have irreplaceable functions for some emergency alarms and will effectively satisfy Family pension needs.


In addition, in traditional smart homes, automatic shut-off of air conditioners, lights, gas, and trespassing are operated by a combined alarm system of cameras and infrared sensors, but many scenarios cannot solve the privacy issues of cameras and the accuracy of infrared. The accuracy and privacy of mmWave radar module products are completely unhindered. At the same time, radar products are highly economical, simple in signal output, and convenient for scene interaction. Due to its penetrating properties, radar can be easily installed in household appliances and lamps and form a complementary linkage with cameras.
