At present, intelligence has become a major trend in the development of the home appliance industry. Various smart sensors are used more and more widely in home appliances, and through network connections, traditional home appliances are transformed into smart home appliances. Smart household appliances mainly refer to a series of smart technologies, such as network and communication technology, smart control technology, smart sensor detection technology, etc., which enable household appliances to realize automation, networking and remote control.


At present, with the continuous development of new low-power, small radar modules and sensors, radar technology has been widely used in intelligent equipment products. For example, in car assisted driving systems, radar has been widely used in the detection of pedestrians and vehicles in front to realize collision avoidance warning. Because the electromagnetic waves emitted by the radar have good penetrability to plastics, bricks, boards and other materials, the radar module can be installed inside the smart electrical product (the front end of the radar monitoring is made of non-metallic materials), because the appearance part will not be blocked and cannot be used, and It can ensure the uniform and beautiful appearance of the product, and other parts, such as infrared sensors, cannot be detected normally.


The radar module can use the artificial intelligence control algorithm to extract the detected characteristics of the human body, and calculate the movement characteristics of the human body, thereby judging the interaction between the person and the smart home appliance (close and far away). Through this method, it can detect whether someone is approaching or far away from the electrical appliance, so as to automatically turn on or off the display, and improve the operating experience of observing the operating state of electrical equipment: when someone enters the sensing detection range, they gradually approach, automatically light up the display, away from the personnel, After leaving the range of the sensing probe, the display is automatically turned off. It can also be achieved that if someone enters the sensing detection range, after the display is lit, it stays next to the appliance. Before the set delay time countdown ends, as long as the person moves slightly, the display will continue to light up until the person leaves the display. It goes off automatically.


Shenzhen Ferry Smart launched the FR58L2MS-3020S(A) microwave induction sensor, which uses the Doppler principle to transmit high-frequency electromagnetic waves through the antenna and receive and process the reflected waves to determine the movement of objects within the coverage area and give corresponding electrical signals. It is widely used in induction lighting, security, small household appliances, smart homes, automatic door control switches, welcome devices and other products, as well as garages, corridors, corridors, courtyards, balconies, toilets and other places that require automatic induction control.


The characteristics of the FR58L2MS-3020S(A) microwave sensor module: farther than the infrared sensor module, the sensing distance is wider, the angle is wider, there is no dead zone, and the lens and lens aging are not affected by temperature, humidity, airflow, dust, noise, brightness, etc. Strong anti-interference ability, can penetrate acrylic, glass and thin non-metallic materials. Built-in MCU, embedded multiple digital filtering algorithms, has higher immunity.


Shenzhen Ferry Smart Co., Ltd. has its own antenna design, core algorithm research and development team that has studied for many years in the millimeter wave radar field, and also has professional RF, communication testing and production and processing capabilities. It has unique advantages in price and program design. Welcome to consult at any time Oh!
