3.2 Application cases of Hangzhou household appliance radar module in smart home

Hangzhou home appliance radar module has many application cases in the field of smart home, the following are a few typical cases:

- Motion sensing and control: the radar module can sense the movement of the human body, and when the person is near or away from the home appliance, it can automatically sense and carry out corresponding control operations. For example, when a person is near the TV, the radar module can make the TV automatically turn on; When leaving, the TV can be automatically turned off for smart energy saving.

Touch alternative: Traditional home appliances usually need to be controlled by buttons or touch screens, but with the use of the radar module, touch alternative solutions can be realized, and the switch and adjustment of home appliances can be controlled by gestures or motion. For example, in the kitchen, the adjustment of oven temperature and time can be controlled by hand gestures, which is convenient and fast.

- Safety monitoring and early warning: the radar module can monitor the safety condition of the home, such as detecting abnormal situations such as smoke, odor, and water leakage, and send alarms or notifications to the user in time to provide timely safety protection.

3.3 Advantage analysis of Hangzhou home appliance radar module in intelligent home appliance control

Hangzhou home appliance radar module has some advantages in intelligent home appliance control:

- No touch: The application of the radar module can achieve touchless control, and the user only needs to approach or leave the home appliance to achieve intelligent control, avoiding the tedious operation of touching the button or screen.

- More intelligent: the home appliance radar module can sense the movement and position of the human body, and through intelligent algorithm analysis, more intelligent home appliance control can be realized. For example, when the user is sitting on the couch, the TV can automatically adjust the volume and channel to provide a better viewing experience.

- Enhance user experience: The application of the radar module can enhance the user's home experience, making the home appliance and the user more interactive and intelligent. Users no longer need to carry out cumbersome operations, home appliances can actively perceive the needs of users, and provide more convenient and personalized services.
