Human presence perception is an extremely important application technology in smart homes. Smart home devices respond or interact accordingly by accurately sensing the presence and state of the human body. However, for a long time, human sensors have generally been inaccurate and unable to monitor static human bodies.
In response to this problem, Infineon Technologies (Infineon for short), a global leader in semiconductor solutions, cooperated with Aqara, a leader in the field of whole-house intelligence, to launch a cost-effective and complete smart home human presence. The solution, the Aqara Human Presence Sensor FP1. The product has been officially launched in Aqara e-commerce and offline Aqara Home smart home experience hall. It is equipped with Infineon's highly accurate XENSIV™ millimeter-wave radar, which enables reliable human presence detection and motion tracking in the home environment. This is also the world's first smart home solution that uses millimeter-wave radar and supports Apple's HomeKit platform, raising the level of human presence awareness to a new level.
In the past, the common human sensor on the market was the PIR passive pyroelectric infrared sensor, which can only detect human movement, but cannot accurately determine whether there is someone in the house. In smart home scenarios, human sensors are often used with smart switches to control lighting. However, if the user keeps a relatively fixed posture for a long time during the process of reading and studying in the study or watching TV in the living room, the human sensor cannot detect it. When the human body moves, there will be problems such as turning off the lights incorrectly. Although many smart cameras on the market also have motion detection and face recognition functions, such products are prone to privacy issues.
The human presence sensor FP1 jointly launched by Infineon and Aqara is the "killer" to solve the above problems. Equipped with Infineon's XENSIV™ millimeter-wave radar chip BGT60TR13C, this solution not only overcomes the weakness of PIR's performance that is easily affected by light and temperature interference, but also can accurately determine whether there is someone indoors without infringing on user privacy. It solves the industry pain points that the static human body cannot recognize. In smart home scenarios, the human presence sensor FP1 based on millimeter-wave radar technology can also perform all-round detection of movement, space, direction, and distance in real time, which greatly stimulates the connection and integration between people, equipment, and space. , so as to realize the intelligent linkage of the whole house.
The BGT60TR13C is small in size, and the architecture is one transmit and three receive. It adopts embedded antenna technology, which meets the requirements of consumer products for miniaturization and low power consumption. Additionally, it has a shorter wavelength for greater precision and sensitivity. Combined with the comprehensive development tools, software algorithms and technical support provided by Infineon, the millimeter-wave radar chip has the ability to accurately identify the subtle movements of the human body, including the tiny displacement of the chest cavity during breathing.
Li Guohao, Application Marketing Director of Infineon Technologies Greater China Power and Sensing Systems Division, said: "The era of smart homes has arrived, and Infineon will work with Aqara to develop new technologies such as millimeter-wave radar in the consumer market. Prospects. The human presence sensor FP1 developed by Aqara based on Infineon XENSIV™ millimeter wave radar chip BGT60TR13C is one of the latest achievements. As Aqara continues to develop new sensors with various sensing functions and seamless linkage Smart home equipment, XENSIV™ millimeter-wave radar chip will have more uses, becoming one of the important forces to help Aqara develop leading smart home equipment and enter the market as soon as possible.
In fact, Infineon has a long-standing partnership with Aqara. In 2020, Aqara signed a software license agreement with Infineon to use Infineon's millimeter-wave radar for new product development. In the stage of product testing and signal adjustment, Infineon also actively shared relevant experience and skills with Aqara to promote the smooth deployment of products. In the future, Infineon will continue to develop cost-effective sensor products, including mmWave radar, with different antennas, packages and software options, enabling smart home device manufacturers such as Aqara to introduce more intuitive sensor products. Functional smart home equipment, thereby promoting the intelligence, automation and energy saving of the home environment.
