Smart Home Appliances

By using radar to detect the presence, distance, movement trajectories, and even subtle movements (such as breathing) of humans or objects, home appliances can “understand” the environmental conditions. For example, an air conditioner can sense prolonged absence of occupants and automatically reduce power consumption or shut down; a refrigerator can recognize when a user approaches and automatically light up the screen; and a range hood can be activated with a wave of the hand and adjust its fan speed accordingly. These features not only enhance the interaction experience but also make appliances more energy-efficient.

Typical applications

Air Conditioner/Fan App

Air Conditioner/Fan App

Radar can monitor a person’s position, distance, and movement status in real time, enabling energy-saving control, wind-free airflow, and automatic wind direction adjustment or avoidance. Compared to timer-based or infrared control solutions, radar supports human presence detection and dynamic tracking, precisely identifying the user’s activity range and automatically adjusting the airflow pattern. This significantly enhances the comfort and energy efficiency of home appliances, creating a smarter human-machine interaction experience.

Advantages

Dynamic perception

Dynamic perception

It can track changes in human body position in real time and precisely control the airflow of home appliances based on the user’s activity trajectory.
Dynamic perception
Human presence detection

Human presence detection

Even when the human body is in a stationary sitting position, the system can continuously and reliably detect without triggering false shutdowns.

When an unmanned state is detected, the system automatically triggers standby or shutdown mode, achieving energy-saving efficiency of over 30%.

On-demand start/stop and adjustment significantly reduce energy consumption.

On-demand start/stop and adjustment significantly reduce energy consumption.

The radar can accurately detect whether there are people indoors, the number of occupants, and their activity status. When no one is present, it automatically reduces the air conditioner’s power—switching to standby or energy-saving mode, or even turning off the fan—thus avoiding the wasteful energy consumption typical of conventional devices that keep running after people have left. As a result, energy consumption can typically be reduced by 20% to 40%.
Precise airflow delivery, enhancing user comfort.

Precise airflow delivery, enhancing user comfort.

Compared to traditional devices that either “deliver fixed airflow” or require “manual adjustment of direction,” radar can precisely locate human positions, enabling air conditioners and fans to direct airflow directly at—or even surround—the area where people are active. This eliminates the frustrating situation of “people being present yet not feeling the breeze,” making it especially suitable for large spaces such as living rooms and offices. The system can intelligently adjust the wind speed based on the distance between the person and the device—for example, automatically reducing the wind speed when a person approaches the fan, thus avoiding uncomfortable direct airflow; and appropriately increasing the wind speed when the person moves farther away, ensuring an optimal coverage area while balancing cooling effectiveness with thermal comfort.
Simplify operations to achieve “hands-free” smart control.

No need to manually turn the device on or adjust the mode—radar automatically detects the environment: When a person enters the room, the air conditioner or fan automatically starts up and switches to the commonly used mode; in summer, it cools, and in winter, it heats. When a person falls asleep, the radar detects reduced movement and automatically lowers the fan speed and adjusts the air conditioner’s temperature to prevent getting chilled. Ideal for seniors, children, or situations where your hands are occupied—such as cooking in the kitchen or working in the study—no need to get up and operate the device, lowering the barrier to use and enhancing convenience.
Strong environmental adaptability, stable and reliable

Strong environmental adaptability, stable and reliable

Unaffected by environmental factors such as light, temperature, and dust, traditional infrared sensors tend to be easily obstructed and can malfunction due to interference from temperature and humidity—especially in environments like kitchens with heavy cooking fumes, bathrooms with high humidity, and bedrooms with dim lighting. In contrast, radar sensors maintain their accuracy and exhibit high stability even under these challenging conditions. Equipped with safety protection features: When the fan is running, if the radar detects a child approaching the fan blades, it can automatically slow down or stop the fan, thereby preventing potential safety hazards. For air conditioners, the radar can monitor whether people remain indoors for extended periods, helping to prevent oxygen deficiency in enclosed spaces (in conjunction with other sensors).
