The new development of smart home millimeter wave radar sensor induction module technology, in the current critical period with the digital transformation of all walks of life, any new technology may become a new infrastructure. Any innovation gene that is born on the basis of the old often turns out to be nothing but empty talk, reexploring the new applications of the old, finding certainty in the unpredictable new era, in order to understand the innovation gene more thoroughly.

Millimeter-wave radar lights up thousands of life scene applications

Traditional products and applications are being reborn for a new era. Speaking of radar, it is impressive that radar has excelled in the military field, but with the development of the security market and smart home in recent years, people have a new understanding of the millimeter wave radar sensor induction module. Millimeter wave has the inherent characteristics of high precision, high sensing and detection. It can not only detect objects, but also provide information such as distance, speed and Angle. At the same time, millimeter waves can penetrate certain materials such as plastics, wall panels and clothing, and are not affected by environmental conditions such as rain, fog, dust and snow. As a result, the application of radar in daily life has blossomed everywhere.

Since the interaction of smart home, smart hotel and elderly residence equipment in 2019, the market has a strong demand for home privacy and the accuracy of linkage. The MMwave radar sensor sensor sensor module product can solve the market pain points after reducing the cost.

With 25 percent of China's population elderly, the issue has become hot. In the field of nursing home, it is necessary to detect the absence of people at home, fall monitoring, apnea, sleep quality and other physiological tests. In addition, the protection of personal privacy also deserves attention. At present, in a family, these gradually become rigid requirements, but also become pain points, urgent technological breakthrough to fill the gap. Smart home millimeter wave radar sensor induction module products are not limited by light and privacy, through the measurement of physiological breathing to determine whether there is someone, because the radar has penetration, can penetrate clothing, glass and wood to sense; At the same time, their products can also judge the physiological state of the elderly by measuring breathing, which has irreplaceable function for some emergency time alarm. Because the millimeter wave radar algorithm is based on Doppler effect and motion state, the continuous iteration of the algorithm can realize the functions of statistical quantity, fall detection and so on, and really effectively meet the needs of families for the elderly.

Why choose the MMW radar sensor induction module?

At present, in the smart home scene, there are three common human body sensors: infrared, ultrasonic and millimeter wave radar sensors. Due to different technical characteristics, product design is often different. For example, because infrared and ultrasonic users can only choose glass shell materials, which can't wrap shells, "millimeter-wave radar is very different from the other two for human sensing applications in smart homes. First, it is more sensitive to the static induction of the human body. Second, the environment is flexible and not affected by temperature, brightness and humidity. Third, the appearance design is more beautiful, can be hidden in the shell for detection, installation without drilling on the surface of the product.

Specific to practical applications, smart home contact physiological detection methods include watches, smart mattresses, smart belts, non-contact physiological detection methods include smart cameras, infrared sensors, etc. Through the research of different users, it is found that these applications are not as good as imagined:

These methods expose many problems in practical application, and the market urgently needs new technology to break through. While the detection of breath is a scene in the smart home and a niche market, for many users it is just a demand. This is also the original intention of our millimeter-wave radar -- focusing on the application of human millimeter wave radar, to become a high-tech company providing breathing monitoring, fall alarm, sleep monitoring.

At present, the sensor induction module of millimeter wave radar radiates electromagnetic waves through the radar to irradiate the human body. After receiving the signal processing, it separates breathing and heartbeat information, basically eliminates all kinds of data acquisition and transmission interference, and output vital sign parameters, motion range parameters and respiratory heartbeat values, giving full play to the technical gene and value of millimeter wave radar.

Millimeter wave radar will become the new inflection point of smart home

At present, most of the mainstream smart home solutions in the market are cameras and smart speakers as core sensors. With the gradual reduction of the cost of millimeter wave radar, the technology will be gradually used in more fields, with low energy consumption, high sensitivity, direction recognition, speed and distance testing and other advantages.

According to the technology maturity curve (the hypecycle) millimeter wave radar sensor induction module technology is in the bubble trough period (TroughofDisillusionment) steadily climb (SlopeofEnlightenment) junction point. In recent years, with the maturity of semiconductor technology in millimeter wave radar chip, millimeter wave chip is rapidly popularized for its characteristics of small area, low cost and high integration. Millimeter wave radar chips are also part of the semiconductor industry, which also follows Moore's law. With the improvement of technology and integration, the cost of millimeter wave radar chip is also falling rapidly. A small millimeter wave chip is at the breaking point of turning technology into a mass product.

In 2003, with the appearance of Bluetooth technology, people began to put high expectations on the application scenarios of Bluetooth technology. Small amount of data, short distance, fast transmission, can convey the sound of several core technical characteristics, make the headset become the most important application of Bluetooth chip. The spread of every new technology in human society follows a similar trajectory. It can be predicted that in the near future, the MMW radar sensor induction module will replace the infrared sensor in the traditional smart home solutions, and may complement the camera to achieve sensor integration. Smart home market is in a period of explosion, the need for better, more accurate solutions to achieve a leap in product strength. The marriage of millimeter-wave radar to the home industry may be like that of Bluetooth technology and headsets.

The advantages of millimeter wave radar sensor induction module are:

1. Strong environmental adaptability: not affected by light, temperature, haze, etc.

2. High precision: speed, distance, Angle and other measurement accuracy is high.

3. More intelligent: Obtain multidimensional data to make decisions more accurate.

4. Convenient: direct output of measurement data

5. Small size: postage stamp size

6. Good security: no privacy disclosure

At present, our millimeter-wave radar products can remotely identify human breath and human posture, and identify living bodies with intelligent induction. There are even fewer companies in this industry in China.

The global radar sensor market was worth $4.5 billion in 2018. With increasing demand for intelligence, radar has a CAGR of 20.04% from 2021 to 2024 and is expected to reach $26 billion by 2024. Of that, $6 billion was for household demand and $2.5 billion was for industrial demand. According to the forecast of Intelligent Research Consulting, the growth rate of smart home scale in the next few years will remain at more than 50%, among which the home millimeter wave radar sensor induction module is expected to reach 10.5 billion yuan in 2024. With the development of millimeter-wave technology, more application scenarios will be expanded, bringing unprecedented convenience to people's life.
